Answer:

4y = 26

Step-by-step explanation:

Given the system of equations:

2y-x=-7 (1)

x+2y= 33 (2)

To find the ordered pair (x, y) that satisfies the equation, we have to solve equations 1 and equations 2 simultaneously, finding the value of x and y as our solution.

Solving equation 1 and equation 2 simultaneously: To find y add both equations together to get:

4y = 26

Divide both sides by 4

4y/4 = 26/4

y = 6.5

To find x put y = 6.5 in equation 1:

2(6.5) - x = -7

x = 13 + 7

x = 20.

Therefore the ordered pair (20, 6.5) satisfies the equation.

Also, 4y = 4(6.5) = 26
