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 - 4a = a + 5y - 4 for a in terms of y.
| \(\frac{11}{14}\)y - \(\frac{3}{14}\) | |
| -8y - 9 | |
| -\(\frac{1}{10}\)y - \(\frac{3}{10}\) | |
| 1\(\frac{2}{7}\)y - \(\frac{4}{7}\) |
