Answer:

x = 11 and y = 4

Step-by-step explanation:

Given equations are :

x+y=15 ...(1)

-2x+5y=-2 ...(2)

We need to solve the systems of equations.

Multiply equation (1) by 2.

2x+2y=30 ...(3)

Adding equation (2) and (3).

-2x+5y+2x+2y = -2+30

7y = 28

y = 4

Put the value of y in equation (1).

x+4=15

x = 11

So, the solution of the given equations are x = 11 and y = 4.
