A father is six time as old as his daughter . after 4 years he will be only four time as old as his daughter will be. what are their present age​

Answer»

Step-by-step explanation:

2 equations and 2 unknowns…

today X is 6 TIMES y

in 4 years time (x + 4) is ( y + 4) x 4

① x = 6y

② x + 4 = 4(y + 4)

③ x + 4 = 4y + 16

sub ① into ③

6y + 4 = 4y + 16

therefore . . .

2y = 12

y = 6

and . . .

x = 6y

so . . .

x = 36
