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 8c + c = c + x - 2 for c in terms of x.
| -\(\frac{5}{7}\)x + \(\frac{9}{14}\) | |
| -4x + 3 | |
| -4\(\frac{1}{3}\)x + 1\(\frac{2}{3}\) | |
| x - \(\frac{2}{7}\) |
