Microwaves use a wheel to spin the food inside and dishwasher, the drawers have wheels
2x-3=-4x+-9
2x-3=-4x-9
negative number and positive number= negative number
2x-3=-4x-9
2x+4x-3=-4x+4x-9
6x-3=-9
6x-3+3=-9+3
6x=-6
Divide by 6
6x/6=-6/6
x=-1
Check answer by using substitution method
2(-1)-3=-4(-1)+-9
-5=-4-9
-5=-5
Answer is x=-1
