Answer:
35, 15
Step-by-step explanation:
Let the present age of the younger person = x
Then the present age of the older person = 50 - x
After (50 - x) - x years, the younger person will be x + [(50 - x) - x} = 50 - x, the older person will be 50 - x + (50 - x) - x = 100 - 3x
Theire age sum will be (50 - x) + (100 - 3x) = 90
150 - 4x = 90
4x = 150 - 90 = 60
x = 60/4 = 15
50 - x = 35
B
add all the like terms together
9+2=11
17x+-5x=12x
