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 4a + 3a = 9a - 2y - 6 for a in terms of y.
| 2y - 1\(\frac{1}{2}\) | |
| y + 1\(\frac{1}{5}\) | |
| -\(\frac{1}{11}\)y - \(\frac{1}{11}\) | |
| 2\(\frac{1}{3}\)y - 1\(\frac{1}{3}\) |
