Asked by Emmanuel

I add 7 to a certain number . I doubled the result. My final answer is 34. What was my number?
Answered by Bosnian
x = Your number

( x + 7 ) ∙ 2 = 34

2 ∙ x + 2 ∙ 7 = 34

2 x + 14 = 34

Subtract 14 to both sides

2 x = 20

Divide both sides by 2

x = 10


( 10 + 7 ) ∙ 2 = 17 ∙ 2 = 34

Let the number be p
(P+7)×2=34
2p+14=34
Collecting like terms
2p=34-14
2p=20
Divide both side by 2
P=10.
