Step-by-step explanation:

5x-2y=11

-2x+5y=17

eqn1×2=10x-4y=22

eqn2×5= -10x+25y=85

21y=107

y=107÷21

5x-2(107/21)=11

5x-(214/21)=11

105x-214=231

105x= 445

x=445/105=

What property does the statement show?<br> (4×8)×3=(8×4)x3

Feliz [49]

This statement shows the Commutative Property of Multiplication. It basically says that now matter order in which you multiply, you still have the same answer because, for example, 4*5=5*4. You can multiply 4 by 5 but you could also multiply 5 by 4 because multiplication is commutative. :)
