How do you solve the equation $- \frac{1}{3} (x - 15) = - 48$ $-1/3(x-15)=-48$ ?

1 Answer

$x = 159$ $x=159$

Explanation:

We are given that:

$- \frac{1}{3} (x - 15) = - 48$ $-1/3(x-15)=-48$

Multiply both sides by $- 3$ $-3$ . Why do I choose $- 3$ $-3$ ?

$(x - 15) = 144$ $(x-15)=144$

Add $15$ $15$ to both sides.

$(x - 15) + 15 = 144 + 15$ $(x-15)+15=144+15$

$x = 159$ $x=159$ .
