Answer:

(4,1)

Step-by-step explanation:

The system of equations is

3x+4y=16......(1)\\-4x-3y=-19.....(2)

Multiply equation(1) by 4 and equation (2) by 3 and then add

12x-12x+16y-9y=64-57\\7y=7\\y=1

Plugging the value of y in equation (1)

3x+4(1)=16\\3x+4=16\\3x=12\\x=4

Hence, the solution to the given system of equation is (4,1)
