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 - 2y - 5 for c in terms of y.
| y + 1 | |
| 4\(\frac{1}{3}\)y - 3 | |
| 1\(\frac{1}{9}\)y - \(\frac{2}{9}\) | |
| -\(\frac{7}{17}\)y + \(\frac{7}{17}\) |
