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