Question

Uche thinks of a number,add7 to it and double the result.
His final answer is 34 what is the original

Answer 1

Let the original number Uche thinks of be \( x \).

According to the problem, Uche adds 7 to the number and then doubles the result:

\[ 2(x + 7) = 34 \]

Now, we can solve for \( x \).

1. Divide both sides by 2:

\[ x + 7 = 17 \]

2. Subtract 7 from both sides:

\[ x = 17 - 7 \]

\[ x = 10 \]

So, the original number Uche thinks of is \( 10 \).
