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