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 2a + 2a = 9a - z + 8 for a in terms of z.
| \(\frac{4}{15}\)z + \(\frac{1}{3}\) | |
| -\(\frac{11}{17}\)z - \(\frac{6}{17}\) | |
| \(\frac{3}{7}\)z - 1\(\frac{1}{7}\) | |
| \(\frac{3}{5}\)z + 1\(\frac{1}{5}\) |
