Use elimination to find the solution to the system of equations.
6x + 4y = -26 2x + 8y = -42

A. (4, -12.5)

B. (-1, -5)

C. (-3.3, 0)

D. (-2, - 4.75)

Respuesta :

apologiabiology
ok, so eliinate the y's
times first equaiton by -2 and add to first

-12x-8y=52
2x+8y=-42 +
-10x+0y=10

-10x=10
divide -10
x=-1
subb back


6x+4y=-26
6(-1)+4y=-26
-6+4y=-26
add 6 both sides
4y=-20
divide both sides by 4
y=-5


(x,y)
(-1,-5)

B
