Question
Answer
adding same number to both sides if 2x=3y, then 2x+1 = 3Y+1   addition property of equality  
🗑
subtracting same number to both sides if 2x=3y, then 2x-1=3y-1   subtraction property of equaity  
🗑
multiplying the same number to both sides if x=y, then 2x=3y   multiplication property of equality  
🗑
dividing the same number to both sides if 2=y, then x/2=y/2   division property of equality  
🗑
a number or expression is equal to itself 4x=4x   reflexive property  
🗑
can flip flop an equation x+5=10, then 10=x+5   symmetric property  
🗑
two numbers equal to the same 3rd number are also equal to each other if x=6 and y=6, then x=y   transitive property  
🗑
if 2 expressions are equal, they can be substituted for each other anywhere if x=4, then 4 can be substituted anywhere x is   substitution property

🗑
If AB=CD, then AB+RT=CD+RT   addition property of equality  
🗑
If <1{<2 and <2{<3, then <1{<3.   transitive property of equality  
🗑
If GH=5 and GH+CD=XY, then 5+CD=XY.   substitution property of equality  
🗑
If AB=PQ, and PQ+MN, then AB=MN.   transitive property of equality.  
🗑
