Question

2) solve:
(A) 5y - 3 = -18
(B) -3x -9 = 0
(C) 4 + 3(z - 8) = - 23
(D) 1 - 2(y -4) = 5

Answer 1

Step-by-step explanation:

(A) 5y-3= -18

5y = -18+3 = -15

y = -3

(B) -3x- 9 = 0

-3x = 9

x = -3

(C) 4 +3(z - 8) = -23

4 +3z - 24 = -23

3z = -23+24-4

3z = -3

z= -1

(D)1-2(y-4)=5

1 - 2y+8=5

-2y = 5-8-1

-2y = -4

y = 2
