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 - 9a = -6a - 6z - 5 for a in terms of z.
| 1\(\frac{3}{5}\)z - 1\(\frac{3}{5}\) | |
| -1\(\frac{1}{3}\)z + \(\frac{1}{2}\) | |
| \(\frac{3}{7}\)z - \(\frac{5}{7}\) | |
| z + \(\frac{2}{9}\) |
