Answer 2

a) z+7=16

Subtract 7 from both sides.

z=16-7

Simplify 16−7 to 9.

z=9

Verify

z+7=16

Let z=9.

9+7=16

Simplify 9+7 to 16

16=16

b) 2q-6=12

Add 6 to both sides.

2q=6

Divide both sides by 2.

q=6/2

Simplify 6/2 to 3

q=3

Verify

2q−6=0

Let q=3

2×3−6=0

Simplify 2×3 to 6

6−6=0

Simplify 6−6 to 0

0=0

c) 3p/10=3

Multiply both sides by 10.

3p=3×10

Simplify 3×10 to 30.

3p=30

Divide both sides by 3.

p=30/3

Simplify 30/3 to 10

p=10

Verify

3p/10=3

Let p=10

3×10/10=3

Cancel 10

3=3
