One number is 12 more than another. The sum of the smaller number and twice the larger number is 39.?

Question

One number is 12 more than another. The sum of the smaller number and twice the larger number is 39.

Any help would be much obliged. Thank you in advance.

Answer 1

x = smaller #
x+12 = larger #
x +2(x+12) = 39
3x+24 = 39
3x = 15
x= 5
x+12 = 17

Answer 2

x = y + 12 2x + y = 39 Then remedy the gadget of equations. using substitution, 2(y + 12) + y = 39 2y + 24 + y = 39 3y = 15 y = 5 for the reason that x is the bigger volume, x = y + 12 = 5 + 12 = 17

Answer 3

Let one number is X
2nd no is= X+12.
X + 2( X+12)= 39.
X + 2X +24=39.
3X= 39-24=15. X=5.
Ans. !st no=5 , 2nd no is 17.

Answer 4

call the small number x, and the large number y. Then we know the following:

x+12 = y
x+2y = 39

This is a system of equations that can be solved in a number of ways. A nifty way is to add 2y to the first equation:

x + 2y+12 = 3y <=> 39+12 = 3y <=> 51 = 3y or y = 17. Therefore, x=5.

Answer 5

Call the small number S and the larger number L.

Then the first sentence tells me L = S + 12.

The second sentence tells me S + 2L = 39.

Solve those two equations, probably by substitution.

Answer 6

x=y+12
y+2x=39 where x is the larger number
substitute y+12 for x in eq 2
2(y+12)+y=39
2y+24+y=39
y=5
x=17

Answer 7

n = x+12

x=5
n=17
17 x 2 + 5=
34+5=
39!!!

Answer 8

1+12=13+12=25+14=39

i think thats the equation hahaha but it makes sense

Answer 9

(S+12) = L
S + 2L = 39
S + 2(S+12) = 39
Solve for S, then add 12 to get L

Answer 10

Let's make "x" the smaller number and "y" the larger number:

x = y - 12
x + 2y = 39

Can you take it from here?
