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 -4c - c = -3c - 2y - 7 for c in terms of y.
| -\(\frac{6}{13}\)y + \(\frac{2}{13}\) | |
| y + 7 | |
| -11y + 7 | |
| -1\(\frac{1}{8}\)y - 1 |
