## Introductory Algebra for College Students (7th Edition)

Plug (-5,2) into the equations to see if it is a solution 2x+3y=-4 2(-5)+3(2)=-4 -10+6=-4 -4=-4 x-4y=-10 (-5)-4(2)=-10 -5-8=-10 -13$\ne$-10 The ordered pair is not a solution of the second equation therefore it is not a solution of the system.
