x%2B3%284x-5%29=5-1%282x-4%29 Start with the given equation



x%2B12x-15=5-2x%2B4 Distribute


13x-15=5-2x%2B4 Combine like terms on the left side


13x-15=-2x%2B9 Combine like terms on the right side


13x=-2x%2B9%2B15Add 15 to both sides


13x%2B2x=9%2B15 Add 2x to both sides


15x=9%2B15 Combine like terms on the left side


15x=24 Combine like terms on the right side


x=%2824%29%2F%2815%29 Divide both sides by 15 to isolate x



x=8%2F5 Reduce

--------------------------------------------------------------
Answer:
So our answer is x=8%2F5 (which is approximately x=1.6 in decimal form)
