Answer 1

1. y-12 =9

y = 12 + 9

y = 21

2. 42=7x

x = 42/7

x = 6

3. 5p-7=28

5p = 28 + 7

5p = 35

p = 7

4. 1.5x+1.3x=-8.4

2.8x = - 8.4

x = - 8.4 : 2.8

x = - 3

5. 4/3w -12=2/3w

w = 18

6. 4 (3q-2)=16q

12q - 8 = 16q

4q = -8

q = - 2

7. -h+4=-h+9

4 = 9

∅

8. t+3t-7=4t-7

4t - 7 = 4t - 7

4t = 4t

0 = 0

9. 1/4(n-6)=1/4-3/2

n = 1

10. 2d+1/6=6(1/3d+1)

2d + 1/6 = 2d + 6

1/6 = 6
