Explain which property of equality used to arrive at the conclusion for the following if x=2 then x+20=22

For this case we have that by definition, the subtraction property of equality establishes that having an equality, any number that is subtracted from one side of it, must be subtracted from the other side. We have: [tex]x = 2[/tex]So, for it to be fulfilled: [tex]x + 20 = 22[/tex]We must subtract "20" on both sides of the equation: [tex]x + 20-20 = 22-20\\x = 2[/tex]Answer: subtraction property of equality
