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 2a + a = -5a - 2z - 3 for a in terms of z.
| -\(\frac{3}{7}\)z - \(\frac{3}{7}\) | |
| -\(\frac{1}{13}\)z + \(\frac{7}{13}\) | |
| -1\(\frac{1}{2}\)z - 3\(\frac{1}{2}\) | |
| \(\frac{7}{11}\)z + \(\frac{9}{11}\) |
