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 -3c - 4c = -2c - 7y - 8 for c in terms of y.
| -\(\frac{1}{2}\)y - 2\(\frac{1}{4}\) | |
| 3y + 8 | |
| -\(\frac{1}{9}\)y - \(\frac{7}{9}\) | |
| -\(\frac{1}{6}\)y - 1\(\frac{1}{2}\) |
