A garden table and a bench cost $742 combined. The garden table costs $42 more than the bench. What is the cost of the bench?

Let the cost of the bench ==B

The cost of the garden table ==B + 42

 

B + B + 42 ==742

2B  +  42 == 742

2B == 742 - 42 ==700

B == 700 / 2 ==350 - cost of the bench

350  +  42 ==392 - cost of the garden table.
