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 + 8a = -6a + 2x + 3 for a in terms of x.
| -1\(\frac{2}{3}\)x + \(\frac{1}{2}\) | |
| 1\(\frac{1}{2}\)x - \(\frac{1}{2}\) | |
| -\(\frac{6}{7}\)x + \(\frac{3}{7}\) | |
| -\(\frac{3}{16}\)x - \(\frac{1}{16}\) |
