I add 7 to a certain number . I doubled the result. My final answer is 34. What was my number?

Answer 1

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

Answer 2

Helpful 🙏🙏

Answer 3

(x+7)/5=34

Answer 4

Ee

Answer 5

10

Answer 6

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.
