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 4a + 2a = -6a + 5z + 2 for a in terms of z.
| -\(\frac{1}{2}\)z + \(\frac{3}{8}\) | |
| \(\frac{3}{10}\)z + \(\frac{1}{5}\) | |
| \(\frac{9}{14}\)z + \(\frac{3}{14}\) | |
| -1\(\frac{6}{7}\)z - 1 |
