Answer:
Step-by-step explanation:
y = -x + 2 -------(i)
2x - y = -5 -----------(ii)
Substitute y = -x + 2 in equation (ii)
2x - (-x + 2) = -5
2x + x - 2 = - 5
3x - 2 = -5 {add 2 to both side}
3x -2 + 2 = -5 + 2
3x = -3 { divide both sides by 3}
3x/3 = -3/3
x = -1
Plug in the value of x in equation (i)
y = - (-1) + 2
y = 1 +2
y = 3
