x*(-5) = -5x
x*(-5) = -5x
5x-4 = 5 ÷ x4 or it can be written as 5/x4.
x is less than or equal to negative 3 or x< or =-3
is the x a variable? because it would be impossible to solve with that information. in not then 150 25*2-5*-20 50--100 (negative and negative equal positive) 150 25x2 - 5x - 20 = 0 (5x + 1)(5x - 5) = 0 therefore; x = -1, or x = 1/5
