Question

HELP PLEASE
Solve the system by substitution
-4.5x - 2y = -12.5
3.25x - y = -0.75

Answer 1

You can also go on mathwey it would solve it fast

Answer 2

from the second equation ,we can know that y=3.25x+0.75
plug it into the first equation
-4.5x-2(3.25x+0.75)=-12.5
-4.5x-6.5x-1.5=-12.5
-11x=-11
x=1
plug it back into the second equation, y=3.25x+0.75=4
the answer would be (1,4)
