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 6a + 6a = 9a + 4z + 8 for a in terms of z.
| \(\frac{2}{3}\)z - 2\(\frac{2}{3}\) | |
| -7z + 5 | |
| \(\frac{5}{12}\)z + \(\frac{1}{2}\) | |
| -\(\frac{11}{16}\)z + \(\frac{3}{8}\) |
