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 -6a + 7a = 5a + 5x - 9 for a in terms of x.
| \(\frac{2}{11}\)x + \(\frac{9}{11}\) | |
| -1\(\frac{4}{5}\)x + \(\frac{2}{5}\) | |
| x - 1\(\frac{1}{5}\) | |
| 13x + 2 |
