Given:
[tex](x+5)\cdot2+7[/tex]
Solve with the property.
Sol:
[tex]=(x+5)\cdot2+7[/tex]
Commutative property of multiplication then:
[tex]=2(x+5)+7[/tex]
Use distribution property.
[tex]=(2x+10)+7[/tex]
Associative property of addition
[tex]=2x+(10+7)[/tex]
So Commutative property of addition not used.
