Use the elimination method to solve the following system. 6x – 7y = –8 –x – 4y = –9
1 answer:
The correct answer is (1,2)
Steps:
Multiply the second equation by 6 in order to eliminate the x variable.
6x-7y= -8
6(-x-4y= -9)
6x-7y= -8
-6x-24y=-54
Add the equations together and solve for y
-31y= -62
Y=2
Substitute y=2 in the original equation
-x-4(2)= -9
-x-8= -9
-x= -1
X=1
