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 - 5c = 8c + 7x - 1 for c in terms of x.
| 2\(\frac{1}{2}\)x - \(\frac{3}{4}\) | |
| -2\(\frac{2}{5}\)x + \(\frac{1}{5}\) | |
| -\(\frac{2}{9}\)x + \(\frac{1}{9}\) | |
| -\(\frac{6}{7}\)x - \(\frac{2}{7}\) |
