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
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 - 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.
