3x-14=2x+10
-2x -2x
1x-14 = 10
+14 +14
1x=24
________
1 1
x=24
hartnn (hartnn):
wow! you nailed it ! :)
now <ABC is just 3x-14 = 3(24) -14 =...?
OpenStudy (anonymous):
so all i do is times it
OpenStudy (anonymous):
so it would be 90
hartnn (hartnn):
3(24) -14 is not 90 ....
did u get how its 3(24)-14 ??
