solve for "x": 0.75(8x-24)-4x=-182
6x-18-4x=-182
2x=-182+18
2x=-200
x=-100
Check: 0.75(8x-24)-4x=-182
0.75(-800-24)-400=-182
0.75 (-824)-400=-182
-618-400=-182?

You added a negative sign in front of 800 when checking.
solve for x
0.75(8x-24)-4x=-182
6x-18-4x=-182
2x=-182+18
2x=-164
x=-82
0.75(8x-24)-4x=-182
6x-18-4x=-182
2x=-182+18
2x=-164
x=-82
While checking it should've been
0.75(-800-24)+400=-182
0.75(-800-24)+400=-182
.75(8x-24)-4x=-182
-492-18+328=-182
-510+328=-182
-182=-182
if x=-82
-492-18+328=-182
-510+328=-182
-182=-182
if x=-82
