Hi again Kevin... same process for this question. You want to work to get the x by itself to solve the equation. Start by adding 13 to both sides and remember -103 PLUS 13 = -90... so you get -9x = -90 Next, divide both sides by -9 and you get x = 10

Incorrect Brian.... the multiplication step clears first before adding or subtracting any numbers.

First, you'll want to distribute the -12 across the parentheses... that will make it 144 = -12x - 60 Second, get the x by itself by adding 60 to both side... that'll make it 204 = -12x Last, divide both sides by -12 ... that'll make it -17 = x
