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