If 33 is added to half of a number :-
[tex] \frac{n}{2} + 33[/tex]
The result is double the number
[tex] \frac{n}{2} + 33 = 2n[/tex]
What is the number ?
[tex] 2(\frac{n}{2} + 33) = 2 \times 2n[/tex]
[tex]n - n + 66 = 4n - n[/tex]
[tex] \frac{66}{3} = \frac{3n}{3} [/tex]
[tex]n = 22[/tex]
Proof :-
[tex] \frac{22}{2} + 33 = 2 \times 22[/tex]
[tex]44 = 44[/tex]

If 33 is added to half of a number :-
\frac{n}{2} + 33
2
n
+33
The result is double the number
\frac{n}{2} + 33 = 2n
2
n
+33=2n
What is the number ?
2(\frac{n}{2} + 33) = 2 \times 2n2(
2
n
+33)=2×2n
n - n + 66 = 4n - nn−n+66=4n−n
\frac{66}{3} = \frac{3n}{3}

n = 22n=22
Proof :-
\frac{22}{2} + 33 = 2 \times 22
