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 8a + 3a = -a + y - 5 for a in terms of y.
| -\(\frac{2}{9}\)y - \(\frac{5}{9}\) | |
| -\(\frac{5}{6}\)y - 1\(\frac{1}{3}\) | |
| -13y + 4 | |
| -4y + 5 |
