PROVE THAT 3 + 3 = 7.

let a=b where a=3, b=7 

a=b 
a(a=b)---------multiply a 
a^2=ab----------distribute 
-(b^2)+(a^2=ab)---------add -(b^2) 
a^2-b^2=ab-b^2-------addition property 
(a-b)(a+b)=b(a-b)-------factor 
a+b=b---------substitute since a=b 
a+a=b 
3+3=7 

to prove it, i just made a and b equal






HOPE IT WILL HELP YOU!!!
