Work Step by Step

To remove the parenthesis, we use the distributive property: $3(2x-1)-6(3x-2)-(x+7)$ =$6x-3-18x+12-x-7$ Now, we collect like terms together and then perform addition/subtraction on them to simplify: $6x-3-18x+12-x-7$ =$6x-18x-x-7-3+12$ =$(6x-18x-x)+(-7-3+12)$ =$(-13x)+(2)$ =$-13x+2$
