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 - 4c = 4c - 3x - 9 for c in terms of x.
| \(\frac{1}{16}\)x - \(\frac{7}{16}\) | |
| -1\(\frac{2}{3}\)x - 1\(\frac{1}{3}\) | |
| -\(\frac{1}{7}\)x + 1\(\frac{2}{7}\) | |
| -\(\frac{1}{7}\)x + \(\frac{2}{7}\) |
