Answer: x = -6
Step-by-step explanation: To solve for x, we first isolate the term containing x which in this problem is 3x. Since 20 is being added to 3x, we subtract 20 from both sides of the equation.
On the left, 2 - 20 is -18 and on the right, the +20 and -20 cancel out.
So we have -18 = 3x.
Since x is being multiplied by 3, we can finish things off by dividing both sides of the equation by 3.
On the right the 3's cancel and on the left, -18 divided by 3 is -6.
So x = -6 is the solution to this equation.
