Answer:
x = 2
y = 3
Step-by-step explanation:
4x - y = 5..........… Equation 1
x + 2y = 8 ............. Equation 2
Make x the subject in equation 2 and substitute it into equation 1
That's
x = 8 - 2y
We have
4( 8 - 2y ) - y = 5
32 - 8y - y = 5
- 9y = - 27
Divide both sides by - 9
We have the final answer as
y = 3
Substitute y = 3 into x = 8 - 2y
That's
x = 8 - 2(3)
= 8 - 6
x = 2
Hope this helps you
