Question

Use the elimination method to solve the system of equations. Choose the correct ordered pair. 

4x + 7y = 60
-4x + 7y = -4

Answer 1

4x + 7y = 60
-4x + 7y = -4
------------------add
14y = 56
y = 56/14
y = 4

4x + 7y = 60
4x + 7(4) = 60
4x + 28 = 60
4x = 60 - 28
4x = 32
x = 32/4
x = 8

so ur solution is : (8,4)

Answer 2

The value of x and y are 8 and 4 respectively.

How to solve given system using elimination method?

Elimination: A method to solve a system of equation by eliminating or removing one of the variables by making their coefficients same in both equation.

4x+7y=60.....(1)

-4x+7y=-4.....(2)

Add (1) and (2)

We get :

14y=56

y=4

Substitute value of y in (1)

We get: 4x=32

            x=8

Therefore, after elimination we get x and y as 8 and 4.
