Question #38513

Answer 1

Kelvin is 44. Ezra is 14.

Explanation:

K=Kelvin, E=Erva
K is three times her, plus 2, so `K=3E+2`
Sixteen years from now, K is two times her age, so `K+16=2(E+16)`

Substitute the value of K from the first formula
`(3E+2)+16=2(E+16)`
`3E+18=2E+32`
`3E-2E=32-18`
`E=14`

Substitute this into the first formula ans solve for K
`K=3*14+2`
`K=33`
