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 4a + 8a = 2a + 2z + 5 for a in terms of z.
| \(\frac{1}{10}\)z - \(\frac{3}{10}\) | |
| 2\(\frac{3}{8}\)z - 1 | |
| -1\(\frac{4}{13}\)z - \(\frac{6}{13}\) | |
| -3z + 2\(\frac{1}{2}\) |
