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 -a + a = -4a + 5y - 8 for a in terms of y.
| 1\(\frac{1}{3}\)y - 2\(\frac{2}{3}\) | |
| \(\frac{4}{7}\)y - \(\frac{1}{7}\) | |
| -11y + 4 | |
| \(\frac{1}{4}\)y - 2 |
