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 = 6c + 9x - 3 for c in terms of x.
| -12x - 9 | |
| -1\(\frac{1}{2}\)x + \(\frac{1}{4}\) | |
| -\(\frac{1}{3}\)x + \(\frac{1}{3}\) | |
| -3\(\frac{2}{5}\)x + \(\frac{3}{5}\) |
