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