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