Question 58025
 Translate English into Math:
x= One number 
x+12 = the other number is 12 more than another
x+2(x+12) = The sum (addition) of the smaller number and twice the larger
Total= is 39
.
Putting it all together:
x+ 2(x+12)=39
x+2x+24=39
3x+24=39
3x+24-24=39-24
3x=15
x=5
.
The smaller number = 5
The larger number = (x+12)=(5+12)=17
Plugging the values back into the original equation:
x+ 2(x+12)=39
(5)+ 2((5)+12)=39
(5)+ 2((5)+12)=39
5+2(17)=39
5+34=39
39=39 [checks out]
