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 - 6a = -7a + 9y + 1 for a in terms of y.
| -3y - 2 | |
| 15y + 1 | |
| y + 3 | |
| -1\(\frac{1}{4}\)y - \(\frac{5}{12}\) |
