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 4a - 6a = -8a + 9z + 6 for a in terms of z.
| 1\(\frac{1}{4}\)z + \(\frac{1}{2}\) | |
| \(\frac{10}{17}\)z - \(\frac{3}{17}\) | |
| \(\frac{1}{9}\)z - 1 | |
| -1\(\frac{1}{5}\)z + \(\frac{3}{10}\) |
