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 7a - 5a = -5a + 3z - 5 for a in terms of z.
| 1\(\frac{4}{7}\)z - \(\frac{4}{7}\) | |
| 1\(\frac{1}{6}\)z + \(\frac{5}{12}\) | |
| \(\frac{1}{4}\)z + \(\frac{1}{12}\) | |
| \(\frac{2}{3}\)z - \(\frac{5}{12}\) |
