l8m-3l = 7 solve

OpenStudy (anonymous):

what is this ??? can't u even do this simple one ??

OpenStudy (anonymous):

r these absolute signs??

OpenStudy (anonymous):

yep

OpenStudy (anonymous):

18m - 31 = 7 Then, 31+7 = 18m 38 = 18m m = 38/18 m=2.11

OpenStudy (coolcat):

m=38/18 2 2/18

OpenStudy (anonymous):

You can restate it as a reduced mixed fraction: 2 1/9

OpenStudy (anonymous):

ok then 8m-3=plusminus7 8m=3plusminus7 1)8m=10 m=10/8=5/4 and2) 8m=-4 m=-4/8=-1/2

OpenStudy (anonymous):

you need to solve two equations \[|8m-3|=7\implies 8m-3=7 \text{ or } 8m-3=-7\] solve them separately

OpenStudy (anonymous):

-1/2 and 5/4

OpenStudy (anonymous):

righttttttttttttttttt

OpenStudy (anonymous):

l8m-3l = 7 the ans: 8m-3=7 or -(8m-3)=7 m=5/4 or m=-1/2

OpenStudy (anonymous):

5/4
