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