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 -8c + 5c = 3c - x - 7 for c in terms of x.
| 5\(\frac{1}{2}\)x - \(\frac{1}{2}\) | |
| \(\frac{6}{11}\)x + \(\frac{7}{11}\) | |
| -1\(\frac{6}{7}\)x - \(\frac{6}{7}\) | |
| x + \(\frac{3}{5}\) |
