Answer:
(4,1)
Step-by-step explanation:
The system of equations is
[tex]3x+4y=16......(1)\\-4x-3y=-19.....(2)[/tex]
Multiply equation(1) by 4 and equation (2) by 3 and then add
[tex]12x-12x+16y-9y=64-57\\7y=7\\y=1[/tex]
Plugging the value of y in equation (1)
[tex]3x+4(1)=16\\3x+4=16\\3x=12\\x=4[/tex]
Hence, the solution to the given system of equation is (4,1)
