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 - 7c = -9c - 2x + 2 for c in terms of x.
| \(\frac{4}{7}\)x - \(\frac{1}{7}\) | |
| \(\frac{6}{13}\)x - \(\frac{7}{13}\) | |
| \(\frac{5}{7}\)x + \(\frac{2}{7}\) | |
| \(\frac{11}{13}\)x + \(\frac{9}{13}\) |
