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 - 5a = 3a - 2z + 6 for a in terms of z.
| \(\frac{1}{2}\)z + 1 | |
| -z - \(\frac{1}{9}\) | |
| \(\frac{5}{11}\)z - \(\frac{9}{11}\) | |
| \(\frac{9}{10}\)z + \(\frac{3}{5}\) |
