Question

Five more than twice a number is 15 less than four times the same number. Find
number.​

Answer 1

Answer:

10

Step-by-step explanation:

let the number be 'x'.

twice of the number = 2x

five more than twice of the number  = 2x+5

four times the number = 4x

15 less than four times of the number  = 4x -15

now according to the condition, 2x+5 = 4x-15

4x-2x =5+15

2x =20

x =10

Answer 2

Answer:

Required number = 10

Step-by-step explanation:

Let the number be x.

According to the problem given,

Five more than twice a number is 15 less than four times the same number

$2x+5 = 4x-15$

$\implies 2x-4x = -15-5$

$\implies -2x = -20$

$\implies x = \frac{-20}{-2}\\=10$

Therefore,

Required number = x = 10
