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 - 2a = -5a - 5z - 5 for a in terms of z.
| 2\(\frac{1}{6}\)z - \(\frac{1}{2}\) | |
| z - \(\frac{3}{4}\) | |
| -\(\frac{3}{8}\)z + 1\(\frac{1}{8}\) | |
| -\(\frac{3}{10}\)z - \(\frac{1}{2}\) |
