Division property of equality is used
Solution:
Given that,
If 3x = 27 then x = 9
We have to find the algebraic property used here
Division property is used here
The division property of equality is a property that tells us if we divide one side of an equation by a number, we must also divide the other side by the same number so that our equation stays the same.
Given equation is:
3x = 27
Divide both the sides by 3
[tex]\frac{3x}{3} = \frac{27}{3}\\\\x = 9[/tex]
Thus division property of equality is used
