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