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 2c - 5c = 9c - 5x + 8 for c in terms of x.
| -13x - 7 | |
| x - 1\(\frac{1}{7}\) | |
| x + 2 | |
| x - \(\frac{9}{14}\) |
