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 = 4c - 3x - 8 for c in terms of x.
| -3\(\frac{2}{3}\)x - 2\(\frac{2}{3}\) | |
| -\(\frac{2}{7}\)x - \(\frac{4}{7}\) | |
| -\(\frac{1}{4}\)x - \(\frac{3}{4}\) | |
| 14x + 1 |
