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