Question

I need help with #2 and 4 please help me T^T

Answer 1

2. w = -90

4. b = 8

Explanation:

Multiply both sides by the reciprocal of the number multiplying the variable.

2.

`-(2)/(3)w = 60`

`-(3)/(2) * (-(2)/(3)w) = -(3)/(2) * 60`

`w = -(180)/(2)`

`w = -90`

4.

`9.6 = 1.2b`

`(1)/(1.2) * 9.6 = (1)/(1.2) * 1.2b`

`8 = b`

`b = 8`
