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 - 3a = 5a - 5z + 2 for a in terms of z.
| -\(\frac{1}{2}\)z - \(\frac{1}{2}\) | |
| 12z + 6 | |
| -2\(\frac{1}{2}\)z - 1 | |
| 2z - 2 |
