SOŠ 2

The secondary vocational school keeps statistics on the number of students who applied to the school. In 2014 and 2016, a total of 1435 students applied to the school. In 2015, 70 more students applied than in 2014, and in 2016, even 1.5 times more students applied than in 2015.

Calculate how many students applied to the school in 2016

Final Answer:

c =  645

Step-by-step explanation:


a+b+c = 1435
b = 70 + a
c = 1.5 · b

a+b+c = 1435
a-b = -70
1.5b-c = 0

Row 2 - Row 1 → Row 2
a+b+c = 1435
-2b-c = -1505
1.5b-c = 0

Row 3 - 1.5/-2 · Row 2 → Row 3
a+b+c = 1435
-2b-c = -1505
-1.75c = -1128.75


c = -1128.75/-1.75 = 645
b = -1505+c/-2 = -1505+645/-2 = 430
a = 1435-b-c = 1435-430-645 = 360

a = 360
b = 430
c = 645
