Solve by elimination 3x+2y=19 -9x+8y=-29

Alja [10]

Step-by-step explanation:

(3x + 2y =19)(3)

-9x + 8y =-29

9x + 6y = 57 NOTE: we cross here 9x in first

-9x + 8y = -29 we cross here - 9x in second

Since 9x and - 9x are opposite

___________

6y +8y = 57 - 29

14y = 28

Y=28/14

Y=2

Replace y in second equation of this system:

-9x + 8y = - 29

-9x +8(2)= - 29

-9x + 16 = - 29

-9x = -29 - 16

-9x = - 45

X= -45/-9

X=5

Hope this helps..
