0.12+-+0.02+%28x%2B3%29+=+-0.05+%283-x%29 Start with the given equation.


0.12+-+0.02x-0.02%283%29+=+-0.05%283%29%2B0.05x Distribute.


0.12+-+0.02x-0.06+=+-0.15%2B0.05x Multiply.


12+-+2x-6+=+-15%2B5x Multiply EVERY term by 100 to clear out the decimals (this basically moves the decimal 2 spots to the right)


-2x%2B6=-15%2B5x Combine like terms on the left side.


-2x=-15%2B5x-6 Subtract 6 from both sides.


-2x-5x=-15-6 Subtract 5x from both sides.


-7x=-15-6 Combine like terms on the left side.


-7x=-21 Combine like terms on the right side.


x=%28-21%29%2F%28-7%29 Divide both sides by -7 to isolate x.


x=3 Reduce.

Answer:

So the solution is x=3
