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 9c - 4c = c + 3x + 7 for c in terms of x.
| -2x + 2 | |
| \(\frac{15}{17}\)x - \(\frac{5}{17}\) | |
| \(\frac{7}{8}\)x + \(\frac{7}{8}\) | |
| -6x + 2 |
