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