Question 550818: trying to get the right steps to solve 3 problems.
1. -3(x-10) > -x + 5 ( I know the answer is x < 25/2, but she wants it done in set notation and steps shown)
2. 6 + 5z = 12(3-z) (I have no clue where to start)
3. 5 - 4/5x = -11
Thank you

distributed -3
add 3x
divide by 2
{x|x<(25/2)}
.
distributed 12
added 12z
subtracted 6
divided by 17
{z|z=(30/17)}
.
subtract 5
multiply by -1
multiply by 5/4
{x|x=20}
