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