Answer:
11 and 7
Step-by-step explanation:
let x be the bigger number and y the smaller
the sum of the two numbers is 18
x+y=18
x=18-y------i
the sum of the greater number and twice the smaller number is 25
x+2y=25----ii
substituting i in ii
18-y+2y=25
collecting like terms
y=25-18
y=7
subtitute for y in i to get x
x=18-y
x=18-7
x=11
