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 + 9c = -4c + 2x - 6 for c in terms of x.
| 1\(\frac{1}{5}\)x - \(\frac{4}{5}\) | |
| -\(\frac{9}{16}\)x + \(\frac{9}{16}\) | |
| 1\(\frac{3}{4}\)x + 1\(\frac{1}{2}\) | |
| -\(\frac{1}{4}\)x - 1\(\frac{3}{4}\) |
