What type of property is 3x•2y=3•2•x•y

1 answer:

6 0

This is the commutative property because you have 3*x*2*y and you turn the x and the 2 around. The commutative property states that a * b = b * a and therefore x*2 = 2*x.

Nady [450]

-x=-y+2
x=y-2
now substitute iin the first one
y=(y-2)^2+5 (y-2)-3
y=y^2-4y+4 +5y-10-3
y=y^2+y-9
y^2-9=0.
y^2=9
y=3

3-x=2
-x=2-3
-x=-1
x=1

the solution are x=1 and y=3
3=1^2+5 (1)-3
3=1+5-3
3=6-3
3=3
