Answer:
2. w = -90
4. b = 8
Step-by-step explanation:
Multiply both sides by the reciprocal of the number multiplying the variable.
2.
[tex] -\dfrac{2}{3}w = 60 [/tex]
[tex] -\dfrac{3}{2} \times (-\dfrac{2}{3}w) = -\dfrac{3}{2} \times 60 [/tex]
[tex] w = -\dfrac{180}{2} [/tex]
[tex] w = -90 [/tex]
4.
[tex] 9.6 = 1.2b [/tex]
[tex] \dfrac{1}{1.2} \times 9.6 = \dfrac{1}{1.2} \times 1.2b [/tex]
[tex] 8 = b [/tex]
[tex] b = 8 [/tex]
