Which of the following shows the equation after the variables have been collected on the left and the constants have been collected on the right?

Step-by-step explanation:
-2x + 13 = -7x +28
-2x + 7x = 28 - 13
5x = 15
so the equation showing that the variables on the right and the constants in the right is 5x = 15
if you want the answer
5x/5 = 15/5
x = 3
