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 = -4a - 8x + 2 for a in terms of x.
| -\(\frac{1}{10}\)x + \(\frac{1}{5}\) | |
| -\(\frac{4}{9}\)x + \(\frac{4}{9}\) | |
| -\(\frac{11}{18}\)x + \(\frac{7}{18}\) | |
| 2x + 2\(\frac{1}{2}\) |
