Step-by-step explanation:
Let
, we solve for
by algebraic means.
1)
Given
2)
Definition of power/Symmetry of equality
3)
Compatibility with addition/Commutative and associative properties/Existence of additive inverse/Modulative property
4)

5)
Result
Hence, the correct answer is B.
Make an equation
X+X+200=1500
Isolate the variable
2x=1300
X=650
Know that we know what X is, we know that X + 200 will equal the cost of the second appliance
650+850=1500
