Solve -14x-7(4-x)< 3(2x-15). Write your solution using set builder notation. Please show all of your work.

Answer 1

-14x-7(4-x)< 3(2x-15)

get rid of the parentheses:

-14x - 28 + 7x < 6x - 45

collect variables and constants:

-13x < -17
13x > 17
x > 17/13

I'll let you reformulate in the notation of your choice.
