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