how do u know your answer is correct

50 + 30z = 250 + 10z combine like terms by subtracting 10z from both sides and subtracting 50 from both sides.

20z = 200. Divide each side by 20

Z = 10.

To ensure you're correct, plug 10 back into the equation.

50 + 30(10) = 250 + 10(10). Simplify.

350 = 350.

10 is the correct answer.
