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 5a - 9a = -a + 5z - 8 for a in terms of z.
| -\(\frac{7}{13}\)z + \(\frac{3}{13}\) | |
| 1\(\frac{1}{7}\)z - \(\frac{6}{7}\) | |
| \(\frac{6}{11}\)z + \(\frac{2}{11}\) | |
| 2\(\frac{1}{3}\)z - 1\(\frac{1}{3}\) |
