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 -5c - 5c = -8c - 7x + 9 for c in terms of x.
| -\(\frac{2}{3}\)x + 3 | |
| \(\frac{4}{5}\)x + \(\frac{3}{10}\) | |
| x + \(\frac{1}{3}\) | |
| 4\(\frac{1}{2}\)x + 2\(\frac{1}{2}\) |
