I add 7 to a certain number . I doubled the result. My final answer is 34. What was my number?
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
Helpful 🙏🙏
(x+7)/5=34
Ee
10
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.
To find the number, let's break down the problem step by step.
1. Start with a certain number, let's call it "x".
2. Add 7 to this number: x + 7.
3. Double the result: 2 * (x + 7).
4. Set the final answer equal to 34: 2 * (x + 7) = 34.
Now, we can solve for x by isolating it:
2 * (x + 7) = 34
Divide both sides by 2 to simplify:
(x + 7) = 17
Subtract 7 from both sides:
x = 17 - 7
x = 10
Therefore, your number is 10.
