If: x+331 = 133 Then: x = -198
Substitution property.
x=3 y=3.5
transitive property
x+8 8+x
If: x+331 = 133 Then: x = -198
x = 2 is an algebraic equality (Because there is an 'equals'(=) sign) x - 2 is an algebraic expression ( Because there is NO equals sign).
Substitution property.
The distributive property of multiplication over addition.
The commutative property
x - 8
The commutative property states that the terms can be added (or multiplied) in any order, so 8 + 2 equals 2 + 8, OR 8 x 2 = 2 x 8.
x=3 y=3.5
transitive property
x^2 = 64 x = +,- square root of 64 = +,- 8. Thus, x = -8 or x = 8
x+8 8+x
8 x 1 = 8 is the identity property of multiplication which states that anything times one equals whatever you started out with.
