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