Question

does x-4=5 has one solution

Answer 1

Hi there! If you add 4 to both sides, x-4+4=5+4 which gets us 9. Therefore, x-4=5 does have a solution. The solution is 9.

Answer 2

Yes, if you do it correctly by following the Algebraic way you would get:

x-4=5 
you need to find x.
you can do this by subtracting 4 from the x side and adding it to 5.
so it would be x= 5+4
then you jsut add 5 and 4 and you get x.
so x = 9.
