Answer:

Graph A shows the system and solution to the system. Option A is correct.

The sum of Sharon's and John's ages is 70. Sharon is times as old as John. The system of equations regarding the problem is determined.

What is the equation?

The equation is the values of two expressions that are equal.

Let the age of Sharon's be x and Jhon's be y.

The sum of Sharon's and John's ages is 70.

x + y = 70 - - - - (1)

Sharon is times as old as John.

x = 4 y

Now put x = 4y in equation 1

4y + y = 70

5y = 70

y = 70/5

y = 14

Now put y = 14 in x = 4y

x = 4*14

x = 56

The solution of a system of equations is (14, 56) shown in graph 1.

Thus, graph A shows the system and solution to the system. Option A is correct.
