Answer

x=60

Work Step by Step

We need to get the x alone, so we cancel out the addition by subtracting 5 on both sides. This leaves us with the equation $-1/3x=-20$. We need to get the x alone, so we use multiplication to cancel out the fraction, -1/3. Thus, we multiply by the reciprocal, -3/1, to obtain an answer of $x=60$. We plug 60 in for x and confirm that our answer is, indeed, correct.
