Answer 2

I can help you with solving equations. Here is how to solve the equation x-40-50=30:

- First, you need to simplify the equation by combining the constant terms on the left side. To do this, you can subtract 40 and 50, which gives -90. So the equation becomes x-90=30. - Next, you need to isolate x by adding 90 to both sides of the equation. This cancels out the -90 on the left side and gives x=120 on the right side. - Finally, you can check your answer by plugging in x=120 into the original equation and verifying that both sides are equal. You should get 120-40-50=30, which is true.

Therefore, the solution is x=120.
