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 = 4a + 3z + 2 for a in terms of z.
1\(\frac{1}{12}\)z + \(\frac{1}{6}\) | |
5z - 5 | |
\(\frac{10}{11}\)z - \(\frac{1}{11}\) | |
-6z + 2 |
