Answer:
x=−7/5and y=−6/5
Step-by-step explanation:
Step: Substitute−2x−4foryiny=3x+3:
y=3x+3
−2x−4=3x+3
−2x−4+−3x=3x+3+−3x(Add -3x to both sides)
−5x−4=3
−5x−4+4=3+4(Add 4 to both sides)
−5x=7
−5x
−5
=
7
−5
(Divide both sides by -5)
x=−7/5
Answer:
x = 5
y = -1.25
Step-by-step explanation:
3x+4y=10
3x-4y=20
----------------
6x=30
x=5
3(5)-4y=20
15-4y=20
-4y=5
y=-1.25
