They probably thought square rotting was dividing by 2. The correct answer is about 20
3x/5-0.5 = 1.9
+0.5 +0.5
————————
3x/5 = 2.4
x5 x5
___________
3x = 12
x = 4
Y = -2x - 4
y = 2x + 4
-2x - 4 = 2x + 4
-2x - 2x = 4 + 4
-4x = 8
x = -8/4
x = -2
y = 2x + 4
y = 2(-2) + 4
y = -4 + 4
y = 0
solution (-2,0)
