Question

17. Solve the equations:

Answer 1

1)4(x-3)+5=1
4x-4×3+5=1
4x=1+12-5
4x=8 (divide by 4)
x=2

answer is D

2)96=-6(-4-3y)
96=24+18y
-18y=24-96 (divide by -18)
y=-72/(-18)
y=4
answer is B

3)-4y+8=4(2y-2)-2(-16+8y)
-4y+8=8y-8+32-16y
-4y+8y=24-8
4y=16 (divide by 4)
y=4

answer is B

Answer 2

1) D x=2
2) B x=4
3) B y=4
