Answer:
x = 5.5
Step-by-step explanation:
First, you need to distribute the -2:
-2(2+x) = -2x-4
Next you simplify:
x-2x = -x
Then you get all the x values on one side of the equation and everything else on the other side:
7-3x = -x-4 --> 11 = 2x
Finally, you isolate the x by dividing:
2x = 11 --> x = 5.5
