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 10c + 3c = 9c + 6x - 7 for c in terms of x.
| -1\(\frac{3}{10}\)x - \(\frac{1}{10}\) | |
| -\(\frac{3}{13}\)x + \(\frac{6}{13}\) | |
| 3\(\frac{3}{4}\)x - 1\(\frac{1}{2}\) | |
| 3x - 7 |
