4x+9=-3

4x = -3 - 9

4x = -12

then you divide the both sides by the number " 4 " because you want the " x " to be alone .

so it is going to be like this when you divide the both sides by " 4 "

x = -3

Did the presented solution help you understand the process enough to duplicate it on a different question?

do you understand that you need to use inverse operations?? inverse operations are operations that undo the other.(e.g. - 2 + 2 = 0). Now you need to isolate x.
