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 + 6c = -8c + 9x + 4 for c in terms of x.
| -5\(\frac{1}{2}\)x - 3\(\frac{1}{2}\) | |
| 3x + 4 | |
| -\(\frac{6}{7}\)x - 1 | |
| 1\(\frac{1}{10}\)x - \(\frac{4}{5}\) |
