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 -6a + 4a = 3a + 3z - 3 for a in terms of z.
| -1\(\frac{1}{3}\)z + \(\frac{2}{3}\) | |
| \(\frac{1}{9}\)z + \(\frac{1}{3}\) | |
| -\(\frac{4}{5}\)z - \(\frac{1}{5}\) | |
| \(\frac{1}{4}\)z + \(\frac{3}{8}\) |
