-4

Step-by-step explanation:

12x + 4 = 7x -16, Lets start off with subtracting the 4 from the left side

12x = 7x -20. The reason for this is because what you do to one side you must do to the other making -20 on the right side

Now we have to subtract 7x from the right side so we can divide later on making it 5x = -20

Final step is to divide 5x/5 = -20/5 making the answer

x= -4

An easy way to check is to multiply -4 in each spot that has the variable x, so 12(-4) + 4 = 7(-4) -16  the end out would be -44 = -44 meaning all the work is correct
