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