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 7a - 5a = -7a - 6z + 2 for a in terms of z.
| -\(\frac{1}{14}\)z + \(\frac{1}{7}\) | |
| 2z - 1\(\frac{1}{2}\) | |
| -\(\frac{1}{8}\)z - 1 | |
| 1\(\frac{1}{6}\)z + 1 |
