SOLUTION: I am a mom, trying to help my child with her algebra homework. The problem is -5(x-1)<5(x+1). Here is what we've tried so far: -5(x-1)<5(x+1) -5x+5<5x+5 -5x -5x -10x+5<5

Question 256544: I am a mom, trying to help my child with her algebra homework. The problem is
-5(x-1)<5(x+1). Here is what we've tried so far:
-5(x-1)<5(x+1)
-5x+5<5x+5
-5x -5x
-10x+5<5
-5-5
-10x<0
I know this is wrong. I've tried a couple of things, but can't figure out where we're going wrong. Thank you for showing us how to get the right answer.

problem is
-5(x-1)<5(x+1). Here is what we've tried so far:
-5(x-1)<5(x+1)
-5x+5<5x+5
this should be
-5x - 5x < 5 - 5
-10x < 0
Remember the variable has to be positive, multiply by -1,
the inequality has to be reversed when you change signs, so you have
10x > 0
x > 0
