kim's present age --- x
mom's present age -- 47
in 5 years:
kim's age == x+5
mom's age == 52
52 = 2(x+5) + 10
52 = 2x + 10 + 10
x = 16
Kim is now 16
check:
in 5 years , Kim is 21
Mom is 52
what is twice 21 + 10 ?? ,,, mmmh, I get 52
how do you solve? kim's mom is 47 years old. in 5 years her mother will be 10 years older than twice what kim's age will be. how old is kim now?
