Since you don't have a value for "x", you can't multiply or divide through by anything involving x: you don't know if you'd need to flip the inequality.spooky1 said:(x - 6)/2 - (x - 4)/5<-x/4

Instead, start by adding x/4 over to the left-hand side. Convert the fractions to the common denominator of 20, and combine. Then note that you have a positive denominator, so the fraction will be negative when the numerator is negative, and the fraction will be zero when the numerator is zero.

If you get stuck, please reply showing how far you have gotten. Thank you.

Don't try to do too much at once:spooky1 said:I multiplied each term by 20

10x - 60 - 4x - 16 <= -5x

. . . . .20[(x - 6)/2] - 20[(x - 4)/5]

. . . . .10(x - 6) - 4(x - 4)

. . . . .10x - 60 - 4x

But -60 + (-16) = -76, not -44. (Errors don't usually "cancel out", so it's generally better to do the computations correctly the whole way through.)spooky1 said:6x-44=-5x
