# algebra question

## Recommended Posts

This is driving my husband and I crazy. We are trying to solve:

x + .28X = 100,000

We cannot for the life of us remember how to solve a problem like this. Is there an algebra website that would give us a refresher course?

Thanks!

Probably all you need to remember is that X is the same thing as 1X, so the left side of your equation is (1.28)X = 1X + 0.28X

So, divide 100,000 by 1.28 and you get what X equals...78,125

Hope that helps!

That first x means 1x.

So 1x +.28x= 1.28x

1.28x=100,000

Divide each side by 1.28

x=100000/1.28

x=78,125

We are such dummies! I will blame it on being tired, but I am not sure that is it! Thanks for jogging our brains!
