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 = -2c + 7x - 2 for c in terms of x.
| -3x - 7 | |
| -\(\frac{6}{7}\)x + \(\frac{3}{7}\) | |
| \(\frac{1}{5}\)x - \(\frac{9}{10}\) | |
| -4x + \(\frac{2}{3}\) |
