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 -9c + 7c = -6c + x - 1 for c in terms of x.
| -\(\frac{3}{7}\)x + 1\(\frac{2}{7}\) | |
| 2x + \(\frac{1}{3}\) | |
| -1\(\frac{2}{9}\)x + \(\frac{5}{9}\) | |
| -\(\frac{1}{6}\)x - \(\frac{7}{12}\) |
