first lets collect the x's so -12x + x is -11x (think about a number line if you are not sure) then we minus 3x so we get  -14x

-9 + 5 is -4 then if we minus 1 we get -5 so

- 14x - 5

Answer: Combine each like term. Any number in this expression with the variable x is a like term. -12x+1x-3x=-14x. The numbers with no variable are like terms. -9+5-1=-5. The simplified expression is -14x-5.
