Question

Solve for b. −16b=3 What is the answer? a. −18 b. −2 c. 2 d. 18

Answer 1

`\text{If is}\ -(1)/(6)b\ \text{then}\\\\-(1)/(6)b=3\qquad\text{multiply both sides by (-6)}\\\\(-6\!\!\!\!\!\diagup^1)\cdot\left(-(1)/(\\ot6_1)b\right)=3(-6)\\\\(-1)(-b)=-18\\\\\boxed{b=-18}\to\boxed{a.}\\\\\text{If is}\ -16b,\ \text{then}\\\\-16b=3\qquad\text{divide both sides by (-16)}\\\\b=(3)/(-16)\\\\\boxed{b=-(1)/(16)}`

Answer 2

a. −18

Explanation:

-1/6 b =3

Multiply by -6 on each side

-6 * -1/6 b = 3*-6

b = -18
