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 8c - 4c = 7c + 7x - 4 for c in terms of x.
| x + \(\frac{2}{7}\) | |
| \(\frac{1}{10}\)x + \(\frac{1}{5}\) | |
| \(\frac{1}{2}\)x - 1\(\frac{3}{4}\) | |
| 11x - 4 |
