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 5a + 9a = -6a - 5z - 6 for a in terms of z.
| 1\(\frac{2}{7}\)z - 1\(\frac{1}{7}\) | |
| -\(\frac{3}{4}\)z - 1 | |
| -1\(\frac{3}{11}\)z - \(\frac{6}{11}\) | |
| 1\(\frac{1}{3}\)z + 1\(\frac{1}{3}\) |
