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 + c = 9c + 6x + 6 for c in terms of x.
| -\(\frac{6}{7}\)x + \(\frac{3}{14}\) | |
| -\(\frac{5}{7}\)x + \(\frac{3}{7}\) | |
| x + 2 | |
| -2\(\frac{1}{2}\)x - 3 |
