(-4,-2),(3,-2),(2,3)

Answer 1

Answer:

According to Question :

✏ Ages after 5 years :

Age of son = x + 5

Age of father = 3(x + 5)

✏ Ages before 5 years :

Age of son = x - 5

Age of father = 3(x + 5) - 10

❒ Solving Starts :

{\large{:{\longmapsto{\bf{7(x - 5) = 3(x + 5) -10 }}}}}:⟼7(x−5)=3(x+5)−10

{\large{:{\longmapsto{\bf{7x - 35 = 3x + 15 - (10)}}}}}:⟼7x−35=3x+15−(10)

{\large{:{\longmapsto{\bf{7x - 3x= 35 + 15 - (10)}}}}}:⟼7x−3x=35+15−(10)

{\large{:{\longmapsto{\bf{7x - 3x= 35 + 5}}}}}:⟼7x−3x=35+5

{\large{:{\longmapsto{\bf{4x = 40}}}}}:⟼4x=40

{\large{:{\longmapsto{\bf{x = {\cancel \frac{40}{4} }}}}}}:⟼x=440

{\large{\purple{:{\longmapsto{\underline{\overline{\boxed{\bf{X = 10}}}}}}}}}:⟼X=10

❒ Therefore :

{\large{\underline{\pink{\pmb{\underline{\mathfrak{Age \: of \: son = x = 10 \: years}}}}}}}Ageofson=x=10yearsAgeofson=x=10years

{\large{\underline{\pink{\pmb{\underline{\mathfrak{Age \: of \: father = 3x + 10 = 3 \times 10 + 10 = 40 years}}}}}}}Ageoffather=3x+10=3×10+10=40yearsAgeoffather=3x+10=3×10

Answer 2

(-4,-2)

=> x-coordinate = -4

=> y-coordinate = -2

(3,-2)

=> x-coordinate = 3

=> y-coordinate = -2

(2,3)

=> x-coordinate = 2

=> y-coordinate = 3
