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 -3c - 3c = c + 4x - 1 for c in terms of x.
| -1\(\frac{3}{4}\)x + \(\frac{1}{4}\) | |
| -1\(\frac{1}{5}\)x + \(\frac{9}{10}\) | |
| -\(\frac{1}{4}\)x + 1\(\frac{1}{4}\) | |
| x + 4 |
