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 + 6c = 8c + 6x + 1 for c in terms of x.
| x - \(\frac{1}{9}\) | |
| x - \(\frac{5}{13}\) | |
| \(\frac{7}{9}\)x - \(\frac{5}{9}\) | |
| \(\frac{2}{3}\)x - 1 |
