What is Equation?
Two or more expressions with an Equal sign is called as Equation.
Tonya is twice Kevin's age
In three years, Tonya will be 17.
t+3=17
t=14
tonya is now 14 years.
As Tonay is 2 times kevin
t=2k
Substitute t value in above equation.
14=2k
divide both sides by 2
7=k
kevin is 7.
And in another three years, Uncle Rob will be three times Tonya’s age.
17+3, rob is 3 times Tonya
20(3)=60 years.
60, that is in 6 years, so 60-6=54
Kevin is 7 years
Tonya is 14 years
unclerob is 54 years
Hence, Kevin is 7 years, Tonya is 14 years and uncle rob is 54 years

t+3=age in 3 years
t+3=17
minus 3
t=14
tonya is now 14
tonay is 2 times kevin
t=2k
14=2k
divide 2
7=k
kevin is 7
in another 3 years (3+3=6) so t+6, or 17+3, rob is 3 times tonya
20*3=60
60, that is in 6 years, so 60-6=54
kevin is 7
tonya is 14
uncle rob is 54
