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 a + 7a = -8a - x - 1 for a in terms of x.
| \(\frac{2}{17}\)x + \(\frac{6}{17}\) | |
| -\(\frac{3}{4}\)x + \(\frac{1}{4}\) | |
| -\(\frac{8}{9}\)x - \(\frac{1}{9}\) | |
| 1\(\frac{3}{10}\)x + \(\frac{3}{10}\) |
