Elimination Method Use the elimination method to find all solutions of the system of equations.

12. { 2 x − 5 y = − 18 3 x + 4 y =       19

To determine

To find: The solution of given equations using elimination method.

Explanation of Solution

Given:

The given equations are,

2x−5y=−18 (1)

3x+4y=19 (2)

Calculation:

Multiply equation (1) by 3 to make the coefficients of x-term in both equations negative to each other.

3(2x−5y=−18)6x−15y=−54 (3)

Multiply equation (2) by −2 to make the coefficients of x-term in both equations negative to each other.

−2(3x+4y=19)−6x−8y=−38 (4)

Add the equations (3) and (4) to eliminate x, as the coefficients of x-term in both equations are negative to each other
