5y + 1 = 3y + 13
The first step is to reverse any addition or subtraction. Gather all terms being added on one side. Remember that crossing over from one side of the equal sign to the other negates the symbol before the number so plus becomes minus and minus becomes plus. Then move the terms with y in them to the other side. Divide both sides by the constant multiplying y to get the final answer.5y = 3y +13 - 15y = 3y + 125y - 3y = 122y = 12y = 12/2y = 6
