Question

answer the question of IIT Maths
options are 1) -100/7
2) 100/7
3) 200/7
4) 10/7​

Answer 1

Answer:

2) 100/7

Step-by-step explanation:

taking 25 on other side,

20+ x/5 = 21x/5 - 2.6x

(100+ x)/5 + 2.6x = 21x/5

(100 + x + 13x)/5 = 21x/5, cutting 5 on each side,

100= 21x - 14x

x = 100/7
