6x+2
Because you do the ( ) first then it'd be 7x+3x-6-4x+8 so add 7 and 3=10x then do -6+8 which is 2 now you have 10x-4x+2 then 10-4=6 so your answer is 6x+2

Apply the distributive property: 7x + (3x+3. -2) - 4x + 8 Multiply 3 by -2 to get -6: 7x + (3x - 6) - 4x + 8 Remove unnecessary parentheses: 7x + 3x - 6 - 4x + 8 Add 7x and 3x to get 10x: 10x - 6 - 4x + 8 Subtract 4x from 10x to get 6x: 6x - 6 + 8 Add -6 and 8 to get 2: 6x + 2
