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 - 5c = -3c + 7x - 9 for c in terms of x.
| 1\(\frac{5}{7}\)x - 1\(\frac{2}{7}\) | |
| \(\frac{1}{2}\)x + 1 | |
| -14x + 4 | |
| \(\frac{1}{11}\)x - \(\frac{2}{11}\) |
