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