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