Pears

There were pears in the basket. I took two-fifths of them and left six in the basket. How many pears did I take?

Correct answer:

x =  4

Step-by-step explanation:


h - x = 6
x = 2/5h

h - x = 6
x = 2/5·h

h-x = 6
2h-5x = 0

Pivot: Row 1 ↔ Row 2
2h-5x = 0
h-x = 6

Row 2 - 1/2 · Row 1 → Row 2
2h-5x = 0
1.5x = 6


x = 6/1.5 = 4
h = 0+5x/2 = 0+5 · 4/2 = 10

h = 10
x = 4
