Let the two numbers be x and y
As given, the difference of two numbers is 3, so
or
....(1)
And their sum is 25, so
.....(2)
Putting x=3+y in equation (2)



As, x+y=25


So the two numbers are = 14 and 11
it would be adding by 2's because to get from 2 to 4 you have to add two or from 6 to 8 you have to add two also
Answer:
RST = 20
Step-by-step explanation:
a ray that divides an angle into two equal angles is called an angle bisector.
So RSP = PST
3 x -2 = 9x - 26
6x = 24
x = 4
RST = 3x -2 + 9x -26 = 20
