Question

can some please check and see if i did this problem right.
24 > 10 – 2x Solve using the addition and multiplication principles. Be sure to show all of your work.
24 > 10 – 2x = 24 + 2x <10
= 24 - 24 + 2x <10 - 24
= 2x < -14
= 2x / 2 < -14/2
= x < -7

Answer 1

Looks good. but you really don't need to move the x term to the left...it makes it slightly more complicated since you'd be dividign by -2 (which has an additional rule in inequlities)...but your method is correct. :)

Answer 2

Yes, the symbol is wrong

24 > 10 -2x
2x + 24 > 10
2x > - 14
x > -7

Answer 3

oh...noru's right...didn't notice the flip of the symbol on line 2.

Answer 4

i would also avoid using the = sign between lines. best to just put it on the next line. otherwise, it is technically incorrect statements.

Answer 5

but that's a write-up thing, not a mathematics problem

Answer 6
