You collect $20.92 for selling 4 video games and 2 cellphones on a website. Your friend collects $23.44 for selling 4 video games and 3 cellphones on the website. How much do you collect for each video game?
Answers
Answer: D
Step-by-step explanation:
x = video games
y = cellphone
Equation: (1) 4x + 2y = 20.92
(2) 4x + 3y = 23.44
_________________
y = 2.52
4x + 2y = 20.92
4x + 2(2.52) = 20.92
4x = 20.92 - [ 2(2.52) ]
4x = 15.88
x = 3.97
Amount collected for each video game is option D. $3.97.
What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
Let x be the amount got for selling one video game and y be the amount got for selling cellphones.
You collect $20.92 for selling 4 video games and 2 cellphones on a website.
4x + 2y = 20.92
4x = 20.92 - 2y
Your friend collects $23.44 for selling 4 video games and 3 cellphones on the website.
4x + 3y = 23.44
4x = 23.44 - 3y
Equating both the equations,
20.92 - 2y = 23.44 - 3y
Simplifying,
y = 2.52
Substituting y = 2.52 in 4x + 2y = 20.92,
4x = 15.88
x = 3.97
Hence the amount for selling one video game is $3.97.

divide each side by factors that don’t contain the variable
w = 14
Answer:
w=14
Step-by-step explanation:
Let's solve your equation step-by-step.
−5= 1/ 3 (−1−w)
Step 1: Simplify both sides of the equation.
−5= 1/ 3 (−1−w) −5=( 1/ 3 )(−1)+( 1/ 3 )(−w) (Distribute)
−5= −1/ 3 + −1/ 3 w
−5= −1/ 3 w+ −1/ 3
Step 2: Flip the equation.
−1/ 3 w+ −1/ 3 =−5
Step 3: Add 1/3 to both sides.
−1/ 3 w+ −1/ 3 +1/ 3 =−5+ 1/ 3
−1/ 3 w= −14/ 3
Step 4: Multiply both sides by 3/(-1).
( 3 −1 )*( −1/ 3 w)=( 3/ −1 )*( −14/ 3 )
w=14

w=14

Solve the system of linear equations by elimination. Check your solutions.
-5x + 3y = -6
9x - 4y = 1
Answers
We can divide both sides of the equation by 43 to solve for x:
90x / 43 - 47y / 43 = -49 / 43
x = -49/43
We can substitute this value for x back into either of the original equations to find y. Let's substitute it into the first equation:
-5x + 3y = -6
(-5 * -49/43) + 3y = -6
y = (-6 + 5 * 49/43) / 3
y = 17/43
The solution to the system of equations is (x, y) = (-49/43, 17/43).
To check our solution, we can substitute the values we found for x and y back into the original equations and see if they hold true.
In the first equation, -5x + 3y = -6, substituting the values we found for x and y gives us:
(-5 * -49/43) + (3 * 17/43) = -6
This simplifies to -6 = -6, which is true, so the solution holds for this equation.
In the second equation, 9x - 4y = 1, substituting the values we found for x and y gives us:
(9 * -49/43) - (4 * 17/43) = 1
This simplifies to -1 = -1, which is true, so the solution holds for this equation as well.
Therefore, the solution (x, y) = (-49/43, 17/43) is correct.
-45x+3*9y=-6*9
Equation1: -45x+27y=-54
Equation2: -45x-(4*(-5))y=1*(-5)
-45x+20y=-5
Equation1-equation2= 27y-20y=-54-(-5)
7y=-49
Y=-7
9x-4*(-7)=1
9x=1-28
X=-3
(X, y)=(-3, -7)
