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 - 6a = 3a - 6z - 6 for a in terms of z.
| -1\(\frac{3}{4}\)z - 1\(\frac{1}{2}\) | |
| -13z + 6 | |
| z - 1\(\frac{1}{5}\) | |
| 2z + \(\frac{1}{2}\) |
