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 4a - 5a = -2a + 3z + 4 for a in terms of z.
| \(\frac{4}{11}\)z + \(\frac{5}{11}\) | |
| 7z - 4 | |
| 1\(\frac{1}{3}\)z + \(\frac{2}{3}\) | |
| 3z + \(\frac{1}{2}\) |
