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 -9a + 6a = -8a + 6y - 2 for a in terms of y.
| -5y + 3 | |
| 2\(\frac{1}{3}\)y - 1 | |
| y + 2 | |
| y - 3\(\frac{1}{2}\) |
