Question

5 subtracted from two times a number gives 45 what is the number​

Answer 1

Answer:

20

Step-by-step explanation:

let the no. be x

then acc. to ques. 2x-5=45

solving it,we get

2x=45-5

2x=40

x=40/2

x=20

Answer 2

let the number = X

2times a number = 2x

5 subtracted from 2times a number = 2x - 5

it gives = 45

2x - 5 = 45

2x = 45 + 5

2x = 50

X = 50 / 2

X = 25

2times a numbers = 2 × 25

= 50

5 subtracted = 50 - 5

= 45
