Pears

Andrew, Lenka and Rasto have together 232 pears. Lenka has 28 more than Rasto and Rasto pears have 96 more than Andrew. Determine how much each of them has pears.

Correct answer:

A =  4
L =  128
R =  100

Step-by-step explanation:


A+L+R=232
L = 28+R
R = A+96

A+L+R = 232
L-R = 28
A-R = -96

Row 3 - Row 1 → Row 3
A+L+R = 232
L-R = 28
-L-2R = -328

Row 3 + Row 2 → Row 3
A+L+R = 232
L-R = 28
-3R = -300


R = -300/-3 = 100
L = 28+R = 28+100 = 128
A = 232-L-R = 232-128-100 = 4

A = 4
L = 128
R = 100
