-3(2x+4) = 3(x-6)<br> i need steps too
Bezzdna [24]

If you are looking to find the value of x then you have to use distributive property.

1st: multiply -3 by 2x and 4                -3(2x+4)

                                                             -6x -12

2nd: do the same thing on the other side which is multiply 3 by x and -6

                             3(x-6)

                               3x-18

3rd: Then you have  -6x-12=3x-18

                                        +12     +12

add 12 to each side so then you have -6x=3x-6

then divide by -6 on each side and the answer is x= 2/3
