Question

I really need help with these two math problems.

1) y+5x=4;y

2) ax=b;x

Answer 1

Are the questions meaning you are supposed to solve for y in the first one and x for the second?

Your first question is

y + 5x = 4

What do you need to get rid of to have y all by itself on the left-hand side? You&#039;re right! 5x. How do you get rid of it? By performing the opposite operation.

y + 5x - 5x = 4 - 5x

y = 4 - 5x

For your second question, you need to remove the a, right? How do you do that? Well, the question is really a * x, so you do the opposite operation to both sides: divide by a.
