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 = -8a + 7y + 8 for a in terms of y.
| \(\frac{5}{9}\)y + \(\frac{5}{9}\) | |
| 11y + 8 | |
| 4\(\frac{1}{2}\)y + 2\(\frac{1}{2}\) | |
| -8y - 8 |
