3x+7=-x-1
move -x to the other side
sign changes from -x to +x
3x+x+7=-x+x-1
3x+x+7=-1
4x+7=-1
move 7 to the other side
sign changes from +7 to -7
4x+7-7=-1-7
4x=-8
Divide by 4 for both sides
4x/4=-8/4
Answer: x=-2

Answer:
<h3>13 reams</h3>
Step-by-step explanation
Given
Total number of pages to complete the packet = 6400 pages
If each ream contains 500pages, then:
Total number of reams needed = Total pages/number of pages per ream
Total number of reams needed = 6400/500
Total number of reams needed = 12.8
<em>Hence you will need about 13 reams for all the packets</em>
Answer:
$165
Step-by-step explanation:
Rachel works for a clothing store. She is paid $150 every week plus a 10% commission on any clothes that she sells.
Let's find the total amount she is being paid per week
Amount paid originally = $150
Percentage Commission = 10%
Commission = 10% of 150
Commission = 0.1×150

Total amount paid = originally amount + Commission
Total amount paid = $150+$15
Total amount paid =$165
Hence the amount paid to Rachel okus Commission is $165
