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 = 6a + 3z + 6 for a in terms of z.
| 2\(\frac{1}{5}\)z - 1\(\frac{4}{5}\) | |
| 2z + 3 | |
| \(\frac{5}{8}\)z - \(\frac{3}{8}\) | |
| \(\frac{3}{5}\)z - 1\(\frac{4}{5}\) |
