x+3y=-2 and 5x-3y=26 in (x,y) form pls!!
x + 3y = -2
=> x = -2-3y ----iAlso 5x -3y = 26
=> 5 (-2-3y) -3y =26
=> -10 -15y -3y =26
=> -18y = 36
=> y = -2Putting y = -2 in equation i we get,
x= -2 -3(-2)
=> x = -2 +6
=> x = 4Thus The solution is (4, -2)Answer:
(4, -2)
Step-by-step explanation:
Please be sure to share ALL of the instructions. Here you meant "Solve the following set of simultaneous equations and present your solution in (x, y) form."
Note that the first equation features +3y and that the second features 5x - 3y = 26. Simply adding like terms results in our having eliminated the variable y:
6x = 24
Then x = 24/6 = 4
The x coordinate of the solution is 4; Substituting 4 for y in the first equation results in
4 + 3y = -2
which simplifies to 3y = -6. Thus, y = -2, and the solution is
(4, -2)

A percentage is a number or ratio that represents a fraction of 100.
The total cost of the guitar including sales tax and the offer discount is $186.
What is percentage?A percentage is a number or ratio that represents a fraction of 100.
We have,
The regular price of the guitar = $200
Sales tax = 8%
Cost of sales tax = 8/100 x 200 = $16
Offer rate = 15%
Offer = 15/100 x 200 = $30
The total cost of the guitar:
= (200 - 30) + 16
= 170 + 16
= $186
Thus,
The total cost of the guitar including sales tax and the offer discount is $186.
Option A is the correct answer.

13% of the month budget is 2600
13% can be written as 13/100
Now we solve for x
multiply both sides by 100
divide both sides by 13
x=20000
So, the company's total budget is 20,000
