Ответ:
6x + 12 = -6
6x = -6 - 12
6x = - 18
x = -18/6
x = -3
Ответ:
3(2x + 4) = −6
Follow PEMDAS.
First, distribute 3 to all terms within the parenthesis
3(2x + 4) = 6x + 12
6x + 12 = -6
Isolate the x. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
6x + 12 (-12) = -6 (-12)
6x = -18
6x/6 = -18/6
x = -3
-3 is your answer for x
hope this helps
