A) 2m= –16

b) –6z+1 = 1

c) n – 10 = –11

D) –4a+1 = 5

E) 2× – 8 = –2

F) 2× – 8 = –7

Answer 1

a) 2m = -16 → m = -16/2 → m = -8

b) -6z+1 = 1 → z= -6z  = 1-1 → z = -6z = 0 → z = 0/-6 = 0 → z=0

c) n-10 = 11 → n = 11+10 → n = 21

d) -4a + 1 = 5 → -4a = 5-1 → -4a = 4 → a = 4/-4 → a = -1

e) 2x -8 = 2 → 2x = 2+8 → 2x = 10 → x = 10/2 → x = 5

f) 2x -8 = -7 → 2x = -7+8 → 2x = 1 → x = 1/2 → x = 0.5
