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 5a - a = -6a + 4z + 5 for a in terms of z.
| -1\(\frac{4}{7}\)z - 1\(\frac{1}{7}\) | |
| \(\frac{1}{8}\)z + \(\frac{1}{2}\) | |
| \(\frac{5}{11}\)z + \(\frac{5}{11}\) | |
| \(\frac{4}{5}\)z - 1\(\frac{2}{5}\) |
