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 -8a + 6a = a - 7x + 9 for a in terms of x.
| -1\(\frac{2}{11}\)x - \(\frac{5}{11}\) | |
| 1\(\frac{4}{9}\)x - 1 | |
| 1\(\frac{1}{4}\)x + 1\(\frac{3}{4}\) | |
| -4x + \(\frac{1}{2}\) |
