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