do you know what addition property of equality is ?

2. Jenn777

yea im just confused and i need someone to make it clear for me please

3. hartnn

addition property of equality : if x=y then adding 'z' to both sides gives x+z=y+z what did u not get in this ?

4. hartnn

example : if x-3 = y then adding 3 to both sides will give you : x-3+3 = y+3 ---- > x=y+3

5. Jenn777

i have an example solve x -4=20 for x

6. hartnn

add 4 on both sides, what you get ?

7. Jenn777

so it would be x-4+4=20 +4 equals 24 ?! :)

8. hartnn

absolutely correct! good :) x=24.
