Question

8x+2y=16 and -16x-7y=-20 using elimination find the x and y values

Answer 1

8x+2y=16
-16x-7y=-20

Multiply the first equation by 2

Answer 2

So we get
16x+4y=32
-16x-7y=-20

Now we just add both of the equations

Answer 3

We get
-3y=12
y=-4

Answer 4

Now plug in y and solve for x.

Answer 5

x=3

Answer 6

8x+2(-4)=16
8x-8=16
8x=24
x=3

Answer 7

So your answer will be
(3,-4)
