✔ 最佳答案
-4-3m-m < 4m-4
-4 - 4m < 4m - 4
-4 < 8m - 4
0 < 8m
m > 0
first distribute 2x-4x-8-6<0 then combine like words -2x-14<0 upload 14 to the two area -2x<14 then divide by employing -2. keep in mind whilst DIVIDING OR MULTIPLYING by employing A destructive selection turn THE sign! then you definately get x>-7 the 2d 3/4m<-6 the least perplexing way is to multiply by employing the reciprical (basically turn the fraction so it particularly is 4/3) m<-8
Group all of the m terms to the left hand side of the inequality and all constants to the right hand side of the inequality.
-3m -m - 4m < - 4 + 4
-8m < 0
Multiply both sides of the inequality by -1 which requires you to change the direction of the inequality sign:
8m > 0
Divide both sides of the inequality by 8:
m > 0 <<<<<
-4 - 3m - m < 4m - 4
-4m - 4m < 4 - 4
-8m < 0
m > 0/-8
m > 0
