When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve 6a + 5a = 9a + 6y - 3 for a in terms of y.
| -3y - 1 | |
| 2\(\frac{1}{2}\)y + 1\(\frac{3}{4}\) | |
| -\(\frac{1}{3}\)y + 1 | |
| \(\frac{1}{11}\)y + \(\frac{4}{11}\) |
