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 a - 8a = -6a - z - 3 for a in terms of z.
| 2\(\frac{1}{4}\)z + \(\frac{1}{2}\) | |
| z - \(\frac{3}{7}\) | |
| z - 2 | |
| \(\frac{3}{14}\)z + \(\frac{9}{14}\) |
