x\times 2+2=x\times 3-3
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
x\times 2+2-x\times 3=-3
Subtract x\times 3 from both sides.
-x+2=-3
Combine x\times 2 and -x\times 3 to get -x.
-x=-3-2
Subtract 2 from both sides.
-x=-5
Subtract 2 from -3 to get -5.
x=5
Multiply both sides by -1.
