Answer: x = 75
Explanation: In this problem, notice that x is being divided by -5 so to get x by itself, we need to multiply both sides of the equation by -5.
Notice that on the left side, the -5 and -5 cancel
each other out so we're just left with x.
On the right side, we have (-15)(-5) which is 75.
So x = 75.
Finally, remember that we can check our answer by
plugging a 75 back into the original equation.
