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