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