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 - 5c = 6c + 4x - 9 for c in terms of x.
| \(\frac{2}{7}\)x - \(\frac{5}{7}\) | |
| x + \(\frac{1}{11}\) | |
| -1\(\frac{2}{7}\)x + 1\(\frac{2}{7}\) | |
| -x - 1 |
