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 2a - 6a = -6a + 7z - 1 for a in terms of z.
| -\(\frac{2}{3}\)z - \(\frac{2}{3}\) | |
| 1\(\frac{1}{2}\)z - 1 | |
| -\(\frac{2}{3}\)z + 1\(\frac{1}{6}\) | |
| 1\(\frac{5}{8}\)z - \(\frac{1}{8}\) |
