Hard brain teasers for school two old friends, jack and bill, meet after a long time. three kids jack: hey, how are you, man? bill: not bad, got married and i have three kids now. jack: that's awesome. how old are they? bill: the product of their ages is 72 and the sum of their ages is the same as your birth date. jack: cool..but i still don't know. bill: my eldest kid just started taking piano lessons. jack: oh, now i get it. how old are bill's kids?

the eldest is eight and the younger ones are both three
the answer to the question is 3,3, and 8

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

1

4

)=3(6x−9)−8

7x+(8)(x)+(8)(

1

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x

−3
