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