mathstudent55 · Answer

It means that the number makes the equation a true statement.

mathstudent55 · Answer

Example:
5x = 20
Solution: x = 4
When you substitute 4 into x in the equation, you get:
5(4) = 20
20 = 20
As you can see, it makes the equation a true statement. That shows 4 is a solution of this equation.

anonymous · Answer

for example, if i have x + 2 = 2, the only value for x that can make it true is 0 since then 2 = 2
