x=1 and y=-1
Step-by-step explanation:
So, for this systems of equation, I'm using the substitution method.
x+4y=-3 and - 4x+y=-5
Step: Solve x+4y = -3 for x:
x+4y + -4y = -3+-4y (Add - 4y to both sides)
x=-4y-3
Step: Substitute-4y-3 for x in - 4x+y=-5:
-4x + y = -5
-4 (-4y-3) + y=-5
17y + 12=-5 (Simplify both sides of the equation)
17y + 12+-12=-5+-12 (Add - 12 to both sides)
17y = -17
17y
17
=
-17
17
(Divide both sides by 17)
y=-1
Step: Substitute-1 for y in x=-4y-3:
x=-4y-3
x = (-4) (-1) - 3
x=1 (Simplify both sides of the equation)
