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 -9a - 6a = -5a + z + 3 for a in terms of z.
| \(\frac{5}{8}\)z + \(\frac{1}{2}\) | |
| \(\frac{1}{8}\)z - \(\frac{1}{2}\) | |
| -1\(\frac{3}{4}\)z - \(\frac{3}{4}\) | |
| -15z - 6 |
