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 - 5z + 8 for a in terms of z.
| \(\frac{1}{6}\)z + \(\frac{1}{3}\) | |
| 4z + 7 | |
| -2\(\frac{1}{2}\)z - 1\(\frac{1}{4}\) | |
| \(\frac{1}{11}\)z - \(\frac{8}{11}\) |
