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