What is y + 0.4 = 2?

I think that y equls 5 but I am not sure. I would thank anyone to check my answer to see if I am right or not, thank you.

y + 0.4 = 2

y = 2 - 0.4
y = 1.6

To prove it, substitute 1.6 for y in the original problem.

Oh thank you so much!

You are very welcome.

however, if y*0.4 = 2 then y=5

To solve the equation y + 0.4 = 2, we want to isolate y on one side of the equation.

First, subtract 0.4 from both sides of the equation to move the constant term to the other side:
y + 0.4 - 0.4 = 2 - 0.4
This simplifies to:
y = 1.6

So the solution to the equation y + 0.4 = 2 is y = 1.6, not 5.
