Question

Make an equation and solve the equation.

Ricardo is x years old. Natalie's age is 4 more than triple Ricardo's age. Keisha is 2 years older than Natalie. Find each person's age is 7 times Ricardo's age equals the sum of Natalie's and Keisha's ages.

Answer 1

7x=(4+3x)+(2+(4+3x))

Explanation:

Ricardo=x

Natalie=4+3x

Keisha=2+(4+3x)

7x=(4+3x)+(2+(4+3x))

By adding together Keisha and Natalie's ages, you get the sum of their ages. By setting them equal to 7 times Ricardo's age, that would make the equation 7 times Riacardo's age equals the sum of Natalie's and Keisha's ages. I think this is asking you to combine the first function to create the second one that it is asking for.
