7 intelligent comebacks for when conversations turn negative.

The number is 47, calculated as follows:

Let X=the tens digit, and X+3=the ones digit.

X+(X+3)=11

2X=11–3

2X=8

X=4

X+3=4+3=7

Number 47.

Answer:

X-Y=2

11X+11Y=132

X+Y=12

ADD BOTH EQS.

2X=14

X=7

Y=X-2

=5

THEREFORE NUMBER IS 75
