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 - c = -8c + 5x - 3 for c in terms of x.
| -7x - 3\(\frac{1}{2}\) | |
| -4x - 5 | |
| 1\(\frac{1}{2}\)x - \(\frac{3}{4}\) | |
| 1\(\frac{1}{9}\)x - \(\frac{2}{9}\) |
