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 + a = -4a - 3z - 5 for a in terms of z.
| \(\frac{9}{17}\)z + \(\frac{3}{17}\) | |
| -\(\frac{1}{2}\)z + 1 | |
| -\(\frac{4}{11}\)z - \(\frac{5}{11}\) | |
| \(\frac{3}{5}\)z - \(\frac{3}{5}\) |
