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 5c - 5c = 6c - 8x + 9 for c in terms of x.
| -10x + 7 | |
| \(\frac{1}{2}\)x - 4 | |
| 3x - 9 | |
| 4\(\frac{1}{3}\)x - 1 |
