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 -9c - 5c = -5c - 4x - 7 for c in terms of x.
| x - 2\(\frac{1}{3}\) | |
| -\(\frac{1}{10}\)x + \(\frac{1}{5}\) | |
| -\(\frac{1}{4}\)x + 1\(\frac{3}{4}\) | |
| -\(\frac{3}{5}\)x + \(\frac{2}{15}\) |
