Question

5x-(6-2(x+3))solve and explain

Answer 1

5x−(6−2(x+3))

Distribute the Negative Sign

=5x+−1(6−2(x+3))

=5x+(−1)(6)+−1(−2(x+3))

=5x+−6+2x+6

Distribute

=5x+−6+2x+6

Combine Like Terms

=5x+−6+2x+6

=(5x+2x)+(−6+6)

=7x

Answer 2

the answer is =7x
you do the ones in the parentheses first -(6)-(2(x+3))
so distribute parentheses then use apply minus-plus rules to get
-6+2(x+3) then add the 5x to it 5x-6+2(x+3) then you expand it so do
2(x+3) and then use distribute parentheses to make 2x+2*3 then multiple the numbers 2*3=6 
then put it all together 5x-6+2x+6 and solve first group/combine like terms
5x+2x=7x then do 7x-6+6= 0 the 6 plus a -6 to make 0 so the answer is 7x
