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 + 4c = -c + 9x - 2 for c in terms of x.
| -\(\frac{1}{2}\)x - 1\(\frac{1}{2}\) | |
| \(\frac{5}{8}\)x - \(\frac{1}{4}\) | |
| x + \(\frac{2}{3}\) | |
| -3x - 1\(\frac{1}{3}\) |
