Very important question please solve it;(

we know that 120 liked both places and 200 liked Pokhara. To find the number of students that only liked Pokhara 200-120=80 students

we know that 120 liked both places and 220 liked Chitwan. To find the number of students that only liked Chitwan 220-120=100 students

to find number of students that liked neither of places:

add

80+120+100=300. Subtract by total number of students.

350-300=50 students

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
