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 -3a + 6a = 4a - 5x - 5 for a in terms of x.
| 1\(\frac{4}{7}\)x + \(\frac{5}{7}\) | |
| -\(\frac{1}{10}\)x - \(\frac{9}{10}\) | |
| 1\(\frac{2}{9}\)x + \(\frac{1}{9}\) | |
| \(\frac{3}{7}\)x - 1 |
