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 + 5c = -2c + 9x - 9 for c in terms of x.
| -\(\frac{2}{3}\)x + 1\(\frac{1}{2}\) | |
| -\(\frac{5}{11}\)x + \(\frac{1}{11}\) | |
| \(\frac{2}{15}\)x - \(\frac{1}{15}\) | |
| -1\(\frac{5}{6}\)x + 1\(\frac{1}{3}\) |
