-8x+1y=10
-3x+1y=5
-------------------
8x - y = -10
3x - y = -5
------------------
Subtract and solve for "x":
5x = -5
x = -1
----------------
Solve for "y"::
y = 3x + 5
y = 3(-1) + 5
y = 2

- 8x + 1y = 10 ------ eq (i)
- 3x + 1y = 5 ------- eq (ii)
Straight ELIMINATION. Subtract eq (i) from eq (ii), or vice-versa
5x = - 5
x = %28-+5%29%2F5, or highlight_green%28x+=+-+1%29
You should be able to find the value of y
