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 -7a + 4a = -6a + 5y + 6 for a in terms of y.
| -\(\frac{1}{2}\)y + \(\frac{2}{3}\) | |
| -y - 6 | |
| \(\frac{4}{9}\)y - \(\frac{8}{9}\) | |
| y + 6 |
