Question 105768
Let x be the smaller no.
thus, x+12 be the larger number.

The sum of the smaller number and twice the larger number is 39.
therefore the eworking equation should be: x+2(x+12)=39 >>> x+2x+24=39 >>>
3x=39-24 >>> 3x=15 >>> x=5 
Take note that x is the smaller no. and the bigger no. is x+12 or 5+12 or
