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 -7c - 7c = 7c + 9x - 5 for c in terms of x.
| -1\(\frac{1}{3}\)x - 2 | |
| -1\(\frac{1}{7}\)x + \(\frac{5}{14}\) | |
| x - \(\frac{5}{9}\) | |
| -1\(\frac{6}{7}\)x + \(\frac{2}{7}\) |
