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 - 2c = 5c - 2x + 5 for c in terms of x.
| -\(\frac{5}{6}\)x + \(\frac{1}{2}\) | |
| -1\(\frac{1}{8}\)x - 1\(\frac{1}{8}\) | |
| x - \(\frac{5}{12}\) | |
| \(\frac{1}{2}\)x - \(\frac{3}{10}\) |
