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