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