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 9a - 8a = -6a - 2x + 1 for a in terms of x.
| \(\frac{2}{5}\)x + \(\frac{1}{15}\) | |
| \(\frac{2}{9}\)x + \(\frac{4}{9}\) | |
| -2\(\frac{2}{3}\)x + 2\(\frac{2}{3}\) | |
| -\(\frac{3}{11}\)x + \(\frac{7}{11}\) |
