Answer/Step-by-step explanation:
We are trying to isolate the variable.
Multiply both sides by 6 (to get rid of fraction on left side)
10(1-2x)+3x=[9(x-5)]/2 -12
Multiply both sides by 2 (to get rid of fraction on right side)
20(1-2x)+6x=9(x-5)-24
expand
20-40x+6x=9x-45-24
simplify
20-34x=9x-69
move x to one side
20=43x-69
move numbers to one side
89=43x
x=2.0697
