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