For other ppl looking at this question here's the answer.
First you have to put x+8 and 2x-1 equal
Like this x +8=2x-1
Then you have to get x on one side 
So Add 1 to both sides which cancels out the -1
And you have x+9=2x left 
Then subtract x from both sides 
And you get x=9.
hope this helps you; if you need help pm me :).

You have to first get the x by its self by canceling it out so subtract 3 and what you do to one side you do to the other. so that means that -3(-3) two negatives = a positive so thats 6 so what you should have now is    x+6

At a local clothing store, Morgan finds they are having a storewide 40% off sale. She also has a $15 coupon which applies to her
LuckyWell [14K]

Morgan should first take the 40% off then apply the $15 coupon

Lets say her total was $150.

If you take the 40% off first, you get $90

150 * .6 = 90 (since you are taking off 40% you are still paying the rest of the 60% so you can just save extra steps by multiplying by .6 and not .4)

Now you subtract 15 from that value.

90 - 15 = 75 If Morgan takes the 40% off first and then applies the $15 dollar coupon, she has to pay $75.

If she applies the $15 coupon first, her total before the 40% is $135

150 - 15 = 135

The total will come out to be $81

$135 * .6 = 81

If Morgan takes the discount first before applying the coupon she has to pay less and saves the most money.

Answer:

-2\frac{1}{10}

Step-by-step explanation:

So this is simple substitution, \frac{1}{2}(-\frac{1}{5})-\frac{2}{3}(3)=> -\frac{1}{10} - \frac{6}{3}=> -\frac{1}{10} - 2= -2\frac{1}{10}.
