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 2a + a = -5a + 9y - 5 for a in terms of y.
| 1\(\frac{1}{7}\)y - \(\frac{5}{7}\) | |
| y + 7 | |
| -\(\frac{6}{11}\)y - \(\frac{4}{11}\) | |
| 2\(\frac{2}{7}\)y - \(\frac{3}{7}\) |
