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 10a + 2a = 9a - 3y - 3 for a in terms of y.
| \(\frac{1}{4}\)y - 2\(\frac{1}{4}\) | |
| -8y - 9 | |
| -5y - 3 | |
| y + 2 |
