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 - 8a = -7a + 4x - 5 for a in terms of x.
| -1\(\frac{1}{10}\)x - \(\frac{4}{5}\) | |
| -2\(\frac{1}{2}\)x + 1\(\frac{3}{4}\) | |
| 1\(\frac{1}{3}\)x - \(\frac{5}{9}\) | |
| \(\frac{2}{9}\)x + \(\frac{7}{9}\) |
