Answer:
x = 2
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
