X - 2y = 2 <br><br><br> 3x + 2y = -2
WARRIOR [948]

Answer:

x=0

y= -1

Step-by-step explanation:

x−2y=2                 - eq 1

x−2y=2

(3x+2y)+(x−2y)=−2+2

x−2y=2

3x+2y+x−2y=0

x=0

ikadub [295]
True statements:
a) x + y = y + x  ⇒ commutative property of addition
b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

False statements:
c) x - y = y - x  should be: x - y = - y + x
e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
