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 + 9a = -7a + 3y - 3 for a in terms of y.
| y + \(\frac{1}{2}\) | |
| -11y - 4 | |
| -6y - 3 | |
| 1\(\frac{1}{4}\)y - 1\(\frac{3}{4}\) |
