Pears

Andrew, Lenka, and Rastro have together 232 pears. Lenka has 28 more than Rastro, and Rastro 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
