4(x-7)+12 = 12. Solve X.

Use the distributive law to simplify:  4(4x - 7)  =  4·4x - 4·7  =  16x - 28

4(4x - 7) + 12  =  12

16x - 28 + 12  =  12                     Simplify - 28 + 12:

16x - 16  = 12                              Remove -16 by adding 16 to both sides:

16x - 16 + 16  =  12 + 16

16x  =  28                                    Remove the 16 by dividing both sides by 16:

16x / 16  =  28 / 16

x  = 1.75
