    5 take away 1 is just 4.... \[5-1=4 \\ \text{ so } 5(x-y)-1(x-y)=4(x-y) \\ \text{ now just use distributive property }\]

    distributive property goes like this: a(b+c)=a*b+a*c example 5(m+n)=5*m+5*n or can be written as 5m+5n

    did you actually try to use distributive property 4 doesn't equal 1... 5-1 is 4 not 1 5(x-y)-1(x-y)=4(x-y) just apply the distributive law to 4(x-y)

    4(x+y)=4x+4y 4(x-y)=4x-4y we had 4(x-y) so distributing 4 to the terms inside that ( ) gives 4x-4y not 4x+4y
