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 + 6c = 8c - 4x - 7 for c in terms of x.
| x - 1 | |
| \(\frac{1}{2}\)x + \(\frac{1}{4}\) | |
| -10x - 7 | |
| 1\(\frac{5}{11}\)x - \(\frac{4}{11}\) |
