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