Question

Think a number add 10 then multiply by 2 the answer is 100 what is the number

Answer 1

Answer:

40 is the number

Step-by-step explanation:

Let the number be x

Now , After adding 2 followed by multiplying it by 10 ,we get,

2(x+10)=100

or,2(x+10)/2=100/2(dividing both sides by 2)

or x+10=50

or,x+10-10=50-10(subtracting 10 from both sides)

or,x=40
