Question

-9x+2(4x+12)<4(1-3x)-13

Answer 1

-9x+2(4x+12)<4(1-3x)-13

Perform order of operations first. In this case you will multiply the numbers just outside of the #(####).

-9x+2*4x+2*12<4*1-4*3x-13

-9x+8x+24<4-12x-13

Combine the like terms.

-x+24<-12x-9

Now move terms to appropriate sides.

-x+24+12x<-12x+12x-9

11x+24<-9

11x+24-24<-9-24

11x<-33

11x/11<-33/11

When dividing across an inequality you have to flip the sign.

x>-3

Pretty sure that is right, you can plug in any number greater than -3 to check it.
