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 - 3c = 9c + 7x + 3 for c in terms of x.
| -\(\frac{10}{11}\)x - \(\frac{3}{11}\) | |
| \(\frac{1}{4}\)x + \(\frac{7}{8}\) | |
| x - 3 | |
| x - \(\frac{2}{3}\) |
