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