Best ResponseYou've already chosen the best response.0is it really 3x+4=4x? if thats the equation so x=4 and if son is 4years old then 4years ago he was 0

Best ResponseYou've already chosen the best response.0i guess the right equation is 3x4 = 4(x4) while x is the age of son. man is 36 4years ago 32 son is 12 4years ago 8

Best ResponseYou've already chosen the best response.1if x=4 then its the son's age. Man's age is 3x, which is 3*4=12 But let me check... wait....

Best ResponseYou've already chosen the best response.03x4 is the age of man 4years ago 4(x4) 4years ago the age of son is 4x as the man

Best ResponseYou've already chosen the best response.1O ho.... see....3x is the man's age. 4x is the age 4 years before. 3x4 means the age minus 4 years which gives the previous age which is 4x so, 3x4=4x.. when you find x, you get the son's age... Got it @darkmaker ?

Best ResponseYou've already chosen the best response.03x4=4x 4=4x3x 4=x since there is no negative age x is equal to 4 if x=4 son is 4 4years ago 0 man is 12 4years ago 8 equation seems wrong age of man is 4x as age of son 4years ago the age of son must be reduced by 4 also since it was 4years ago anyway I browse the last page of the book and there is the correct answer there son is 12 years old =)
