Answer:
1. x ≤ -8
2. y < -8
3. y < -11
4. n > 10
5. n ≤ -2
6. n ≤ 15
7. n ≤ -5
Step-by-step explanation:
Your goal is to get just the variable on one side of the inequality!
For example, take -2y - 4 > 18.
Add 4 to both sides. So... -2y - 4 + (4) > 18 + (4)
Now you get -2y > 22. Since y isn't by itself, let's divide both sides by -2.
So, (-2y / -2) > (22 / -2)
<u>Anytime you're dividing something by a negative, remember to FLIP THE SIGNS.</u> So instead of a greater than, it will now be a less than sign <.
Now you get, y < -11
<span>Equation at the end of step 1 :</span> (8x + 2 • (x - 7)) - (10x - 14) = 0
<span>Step 2 :</span>Pulling out like terms :
<span> 2.1 </span> Pull out 10x-14
After pulling out, we are left with :
(10x-14) • ( 1 +( (-1) ))
<span>Step 3 :</span>Pulling out like terms :
<span> 3.1 </span> Pull out like factors :
10x - 14 = 2 • (5x - 7)
<span>Equation at the end of step 3 :</span> 0 = 0
(2.75 + 4.25) / 50 = 7/50 = 0.14 = 14% <==
