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 -8a + a = 4a - 8z + 6 for a in terms of z.
| \(\frac{3}{4}\)z - \(\frac{1}{2}\) | |
| 1\(\frac{1}{2}\)z + 1\(\frac{1}{2}\) | |
| z - \(\frac{1}{2}\) | |
| -3\(\frac{1}{2}\)z - 2 |
