Answer
$-13x+2$
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:
$6x-3-18x+12-x-7$
=$6x-18x-x-7-3+12$
=$(6x-18x-x)+(-7-3+12)$
=$(-13x)+(2)$
=$-13x+2$
