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