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 -5c - 4c = 7c + 5x - 2 for c in terms of x.
| \(\frac{1}{3}\)x - \(\frac{1}{3}\) | |
| 5\(\frac{1}{2}\)x + \(\frac{1}{2}\) | |
| \(\frac{15}{16}\)x - \(\frac{1}{2}\) | |
| -\(\frac{3}{4}\)x + \(\frac{1}{6}\) |
