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 -9c + 4c = -7c - 9y + 4 for c in terms of y.
| 5\(\frac{1}{3}\)y - 3 | |
| 6\(\frac{1}{2}\)y - 2 | |
| 2y + 3 | |
| -1\(\frac{1}{3}\)y - 1\(\frac{2}{3}\) |
