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 2a - 4a = -8a - x + 7 for a in terms of x.
| -\(\frac{11}{12}\)x + \(\frac{1}{3}\) | |
| 4x - 3 | |
| -\(\frac{5}{7}\)x + \(\frac{3}{14}\) | |
| \(\frac{3}{10}\)x + \(\frac{7}{10}\) |
