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