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 - 6c = -9c + 7x - 6 for c in terms of x.
| 2\(\frac{3}{5}\)x - 1\(\frac{1}{5}\) | |
| -\(\frac{3}{7}\)x - \(\frac{5}{7}\) | |
| \(\frac{1}{4}\)x + 1\(\frac{1}{2}\) | |
| -\(\frac{3}{8}\)x + \(\frac{5}{16}\) |
