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 -9c - 2c = -4c + 4y + 7 for c in terms of y.
| 1\(\frac{5}{7}\)y - 1\(\frac{2}{7}\) | |
| -1\(\frac{1}{5}\)y - 1\(\frac{2}{5}\) | |
| 2\(\frac{2}{5}\)y + 1\(\frac{3}{5}\) | |
| -13y + 2 |
