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
