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