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 + 2a = a + 6y - 5 for a in terms of y.
| \(\frac{2}{3}\)y - \(\frac{5}{6}\) | |
| 4y - 3 | |
| -\(\frac{8}{9}\)y - \(\frac{4}{9}\) | |
| -\(\frac{8}{11}\)y - \(\frac{8}{11}\) |
