Answer 2

Question:-

If you add Natalie's age and Fred's age, the result is 44. If you add Fred's age to 3 times Natalie's age, the result is 70. Write and solve a system of equations to find old Fred and Natalie are ?

Solution:-

Let us assume that:-

• Natalie's age be 'x'
• Fred's age be 'y'

In Case 1 :-

It is given that => x + y = 44

So, x = 44 - y

In Case 2 :-

It is given that => 3x + y = 70

Now, putting the value of x in Case 2:-

»» 3x + y = 70

=> 3(44-y) + y = 70

=> 132 - 3y + y = 70

=> 132 - 2y = 70

=> -2y = 70 - 132

=> -2y = -62

=> 2y = 62

=> y = 62/2

=> y = 31

Then, Putting the value of y in Case 1:-

»» x + y = 44

=> x + 31 = 44

=> x = 44 - 31

=> x = 13

Hence,

• Natalie's age is 13
• Fred's age is 31
