-180x=\left(32-x-\left(-8\right)\right)\times 100
To find the opposite of x-8, find the opposite of each term.
-180x=\left(32-x+8\right)\times 100
The opposite of -8 is 8.
-180x=\left(40-x\right)\times 100
Add 32 and 8 to get 40.
-180x=4000-100x
Use the distributive property to multiply 40-x by 100.
-180x+100x=4000
Add 100x to both sides.
-80x=4000
Combine -180x and 100x to get -80x.
x=\frac{4000}{-80}
Divide both sides by -80.
x=-50
Divide 4000 by -80 to get -50.
