Answer:

x = 2

Step-by-step explanation:

The system of equations is:

x = y - 5............................(1)

2x + y = 11........................(2)

Substitute equation (1) into equation (2)

2(y - 5) + y = 11

2y - 10 + y = 11

Collect like terms

2y + y = 11 + 10

3y = 21

y = 21/3

y = 7

Substitute y = 7 into equation (1)

x = y - 5

x = 7 - 5

x = 2
