- 4x + 3y = 23x- 9y =3Is (4,1) a solution of the system?
Accepted Solution
A:
Answer:- 4x + 3y = 2we multiply the equation by 3-12x+9y =6we add the equations : -12x+9y =6 + 3x- 9y =3 --------------------- -9x+0 = 9then -9x = 9x= 9/-9x=-1we replace this result in the first equation.- 4x + 3y = 2-4(- 1)+ 3y =24 +3y =23y= 2-43y =-2y=-2/3solution: (-1, -2/3)the answer to the question is: NO
