symmetric property of equality
X= x
If: 14x = 56Then x = 56/14Therefore: x = 4
Isolate the variable. Get it by itself. 9+11x=89+x 9+11x-1x=89+x-1x Subtraction property of equality 9+10x=89 9+10x-9=89-9 subtraction property of equality 10x=80 x=8 division property of equality.
symmetric property of equality
symmetric property of equality
The reflexive property, which is a property of all equivalence relations. Two other properties, besides reflexivity, of equivalence relations are: symmetry and transitivity.
X= x
If: 14x = 56Then x = 56/14Therefore: x = 4
Isolate the variable. Get it by itself. 9+11x=89+x 9+11x-1x=89+x-1x Subtraction property of equality 9+10x=89 9+10x-9=89-9 subtraction property of equality 10x=80 x=8 division property of equality.
Transitive property: If 8 equals x and x equals y, then 8 equals y.
if x+5=9 than x=4 solved by subtraction property of equality check by substation property 4+5=9
13+x=106 x+13=106 commutative property of addition x+13-13=106-13 additive property of equality x=93 substitution property
transitive property
By the reflexive property of equality, a number is equal to itself: a = a. For example, 2 = 2, 3 = 3, -3/4 = -3/4 etc. Since x is a variable that represent numbers, then x is equal to itself: x = x. Suppose that x = x is a false statement. If x = 1, by the substitution property of equality, 1 can replace x. So we have 1 = 1 which is a true satement. Therefore, x = x cannot be a false statement. Thus, x = x is true. If: x = x Then: x-x = 0
The Abelian property or commutative property.
