Answer:
21 and 28
Step-by-step explanation:
1) calling the smaller number x and the larger y we can write two equations.
x+y=49 and y+2x=70
2) by reordering the first to read x= 49-y we can then plug it in as the x in the second equation.
y+2(49-y)=70
3) we can then distribute
y+98-2y= 70
and then simplify
y=28
4) then we need to plug y back into the first equation to find the value of x
x+(28)=49
-28 -28
x = 21
5) the numbers are 21 and 28
