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 -a + 2a = -6a + 6z - 3 for a in terms of z.
| \(\frac{2}{3}\)z - \(\frac{7}{15}\) | |
| \(\frac{4}{5}\)z - \(\frac{3}{5}\) | |
| -\(\frac{5}{9}\)z + \(\frac{1}{9}\) | |
| 3z + 2\(\frac{1}{3}\) |
