- say number is 10a+b .
so , a+b=12 and a-b=6
so , a=9 and b = 3 after solving the equation.
so , the number is 93.

- x+y=12
x-y=3
x=9
y=3
9+3=12
9-3=6
therefore no. is 93 - 10 years agoHelpfull: Yes(1) No(0)
- x+y=12
x-y=6
solve those equations
we get x=9 and y=3
so the number is xy= 93 - 10 years agoHelpfull: Yes(0) No(0)
- 93
10x+y=12
10x-y=6
solving above equations we get x=9;y=3 - 10 years agoHelpfull: Yes(0) No(0)
- the two digit no is 93
let no be xy=> x+y=12
x-y=6
2x=18
x=9
y=3
ans= 93 - 10 years agoHelpfull: Yes(0) No(0)
- X+Y=12
X-Y=6
ADDING BOTH EQS
2X=18, X=9
Y=12-9=3
NUMBER IS 93 - 10 years agoHelpfull: Yes(0) No(0)
