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 -4c - 8c = 3c + 4x - 8 for c in terms of x.
| 6x + 8 | |
| 1\(\frac{1}{5}\)x - \(\frac{1}{2}\) | |
| -1\(\frac{5}{7}\)x + 1\(\frac{1}{7}\) | |
| 2\(\frac{1}{2}\)x - 1\(\frac{1}{3}\) |
