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 + 3x - 5 for c in terms of x.
| -5x + 3 | |
| -\(\frac{1}{12}\)x + \(\frac{5}{12}\) | |
| -\(\frac{12}{13}\)x - \(\frac{2}{13}\) | |
| x + \(\frac{1}{9}\) |
