Answer:
Allie
x=4
Explanation:
Allie, because you need to combine the x's in order to solve the equation.
You need to add -12x to 8x which equals 20x-19=61 then you need to add 19 to 61 which gives you 80. Now, your equation is 20x=80. Finally, you need to divide by 20 on both sides which gives you x=4.
