Solve for x in this inequality. Show all your work and<br> graph your solution.<br> 4(x-3)&lt;2x-4
maw [93]

Answer:

x<4

Step-by-step explanation:

To solve for x in the inequality equation, the terms should be rearranged such that x is on one side and integers are on the other side.

First, expand 4(x-3).

This will obtain:

4x - 12 < 2x - 4

Now, shift x terms and integers on each side.

4x - 2x <  - 4 + 12

After simplifying, it will get:

2x < 8

Finally, we can solve for x.

x < 4

We can also draw the respective graph (please don't mind my drawings), where the area shaded in green is the range.

17-2p=2p+5+2p ? I’m so confused
svp [43]

Answer:

Step-by-step explanation:

Let's do like-terms first which on the right side has the 2p:

17-2p=4p+5

Then make the variables on one side:

17=4p+2p+5

17=6p+5

Let's put that 5 on the other side:

17-5=6p

12=6p

Lastly, divide 6 to get a final remaining p.

12/6=p

2=p

Hope you understand :)

Help on this one as well ii manged to get an answer but If you understand it or im wrong an you please explain ! thank you !!
AnnZ [28]
Almost got it!

x + 3 = 3(y + 2)/2 [Multiplied both sides by 3]
so x + 3 = (3y + 6)/2
2(x + 3) = 3y + 6 [Multiplied both sides by 2]
2x + 6 = 3y + 6
2x = 3y [Subtracted 6 from both sides]
x = 3y/2 [Divided both sides by 2]
x/3 = y/2 [Divided both sides by 3]

So you wrote y/3 instead of y/2 
Hope this helped!
