Kevin is 3years older than Matt,Two years ago Kevin was 4Times as old as Matt.how old is Kevin now

Answer 1

Now: eqtn 1) K = M + 3 and 2 years ago: eqtn 2) K -2 = 4(M-2)

Sustitute K's age for M's in eqtn 2:

M + 3 - 2 = 4(M - 2) muyltiply out

M +1 = 4M - 8 combine like terms

9 = 3M divide

3 = M

Therefore K is M + 3 = 6

Answer 2

K=3+M

two years ago

K-2 = 4(M-2) = 4M-8

3+M-2 = 4M -8

m+1 = 4M-8

3M =9

M=9/3 = 3 years old

K=3+3 = 6 years old

Two years ago Kevin was 4 year old and 4 times Matt who was then 1 year old
