To solve the equation 5a + 5 = 6a - 7, you first want to simplify both sides. Start by combining like terms on each side of the equation. Add 7 to both sides to isolate the variable terms on one side. Then, subtract 5a from both sides to solve for the variable a. The final answer is a = 12.
7a + 4 = 5a + 7 7a = 5a + 3 2a = 3 a = 3/2
5a = -5a + 5Add 5a to each side:10a = 5Divide each side by 10:a = 5/10 = 1/2
