If we add7 to twice a number, we get49. Find the number.
Solve for the value of the required number.
Let the number be x
⇒2x+7=49⇒2x=49–7⇒2x=42⇒x=21
Hence, the required number is 21.
1) if we add 1 to any even number we get a_______number.
2) if we add 1 to any odd number we get an______number.
3) if you add an even number to an odd number we get an.
If we add 1 to a natural number, we get the next natural number.
On solving 'Add two to a number and subtract twice the so obtained sum' we get,
