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 -3a - 8a = -4a + 9z + 4 for a in terms of z.
| -\(\frac{4}{13}\)z - \(\frac{3}{13}\) | |
| 17z + 4 | |
| 2z + 1 | |
| 1\(\frac{3}{11}\)z + \(\frac{6}{11}\) |
