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