Question

What does it mean for a number to be the "solution" to an equation?

Answer 1

"Solution" is something which makes the equation true!!
Left hand side = right hand side.

CAN YOU GIVE ME AN EXAMPLE PLEASE

Answer 3

e.g.

2x + 1 = 5
x = 2

Now if we replace 2, we will get:

2(2) + 1 =5
5 = 5

So 5 is the solution.
