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