Question

Solve the system by substitution -4.5x-2y=-12.5
3.25x-y=-.75

Answer 1

-4.5x -2y=-12.5 3.25x -y =-75 Therefore this would be 3.25x -y=-75 dividing -4.5x -2y=12.5 0.72x +2= 6 Therefore it would be 0.72x +2=6 Then you group like terms which is 0.72x=6-2 0.72x=4 Divide both sides by 0.72 x=0.18
