linear system

Question

is (2,-3) the solution for the following linear system. 3x+6y=-12 and 2y-8x=-22.

Answer 1

Given (2,-3)

Linear System 3x+6y = -12 and 2y-8x = -22

Substitute the above coordinate in given system.

3(2)+6(-3) = -12 and 2(-3)-8(2) = -22

6-18 = -12 and -6-16 = -22

-12 = 12 and -22 = -22

The above point  satisfy the system.

So (2,-3) is solution of given linear system.
