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