A linear function has the equation 4x+6y= 50. What is the
value of a when y = 3?
x =
Answer: x=8
Step-by-step explanation:
4x+6y=50
4x+6(3)=50
4x+18=50
4x=32
x=8
The value of x when y = 3 in the linear function 4x + 6y = 50 is x = 8.
Use the concept of linear fucntion defined as:
The formula for a linear function is f(x) = mx + b, where m and b are real values. The slope-intercept form of a line is represented by the equation,
y = mx + b.
The given linear fucntion is:
4x+6y= 50
To find the value of x when y = 3,
Substitute y with 3 in the equation and solve for x.
4x + 6(3) = 50
4x + 18 = 50
To isolate x,
Subtract 18 from both sides:
4x = 50 - 18
4x = 32
Now we divide both sides by 4:
x = 32/4
x = 8
Hence,
When y = 3, the value of x in the linear function 4x + 6y = 50 is 8.

If the sum of a number and three is tripled the result is one less than twice the number. Find the number.
If the sum of a number and three is tripled the result is one less than twice the number. The number is 14.
Write an equation and expressions by defining variables first.
"a number" is x.
Then "the sum of a number and three is tripled" is 3(x+3).
And "five less than twice the number" is 2x - 5.
Set them equal and solve for x.
3(x+3) = 2x -5
3x+9 = 2x-5
x+9 = -5
x = -14

On being asked her age, Shalu replies, 'My brother was born 2 years before me and my sister 4 years after me, and the sum of their ages is 30 years." How old is Shalu?
Shalu is 16 years old.
The equation can be defined as a mathematical term that refers to a situation in which several factors must be considered. It is defined as the state of being equal and is frequently represented as a math expression with equal numbers on either side.
Two expressions joined by an equal sign form a mathematical statement known as an equation.
Shalu's brother was born 2 years before Shalu.
Shalu's sister was born 4 years after Shalu.
And the sum of Shalu's brother and sister's age is 30 years.
Let x be the age of Shalu.
As Shalu's brother was born 2 years before her = x + 2
As Shalu's sister was born 4 years after her = x - 4.
Therefore,
x + 2 + x - 4 = 30
2x - 2 = 30
Adding 2 on each side of the equation,
2x -2 + 2 = 30 + 2
2x = 32
Dividing each side of the equation by 2.
2x / 2 = 32 / 2
x = 16
Therefore, Shalu is 16 years old.
