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 + 5a = a - 2z + 2 for a in terms of z.
| -\(\frac{3}{4}\)z - \(\frac{1}{4}\) | |
| -3\(\frac{1}{2}\)z + 1 | |
| -2z + 3 | |
| -9z + 7 |
