Answer:
x = -8
Step-by-step explanation:
You would solve the parenthesis first by distrubuting the two to the things inside the parenthesis:
2 times 4x and 2 times -5
Once you multiply the 2 to each of the numbers the parenthesis are no longer needed.
8x - 10 + 11 = -63
Next you would want to simplify the -10 and 11
-10 + 11 = 1
Now you have simplified the the -10 and 11 and have gotten 1
8x + 1 = -63
Now you want to subtract the one on both sides in order to get it the variable by itself.
-1 + 8x + 1 = -63 -1
The one on the left side would then cancel out and 8x would be left on the left. And for the irght side you would combine the -63 and -1 to make -64.
8x = -64
Now you have to get the variable by itself and divide by 8 on both sides to cancel the 8 on the left side out. And when you do that you should get.
x = -8
