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 c + 8c = 7c - 9x - 6 for c in terms of x.
| -\(\frac{2}{5}\)x - \(\frac{3}{5}\) | |
| 2\(\frac{5}{6}\)x + 1 | |
| x + \(\frac{7}{10}\) | |
| -\(\frac{1}{2}\)x + 2\(\frac{1}{4}\) |
