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