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

18 = 2x9 = 2x3²

30 = 3x10 = 2x3x5

GCF (18, 30) = 2x3 = 6

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)
