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 -9c + 8c = -8c + 6x - 3 for c in terms of x.
| 2x + 3 | |
| -1\(\frac{1}{3}\)x + 1\(\frac{2}{3}\) | |
| -3\(\frac{2}{5}\)x - 1\(\frac{1}{5}\) | |
| -\(\frac{15}{16}\)x - \(\frac{9}{16}\) |
