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