x=-8 because when you distribute -2 with x and 3, you get -2x -6, and that will give you the simplified version: -2x-7=9

You add 7 to both sides so that the 7 cancels out, and you get -2x=16

Then, you divide -2 by both sides to get x by itself, and the result is x= -8

Answer: -8

Step-by-step explanation: First add one to both sides. Now you're left with −2(x+3)=10. Then divide both sides by 2 and simplify 10/2 to 5. Next, subtract 3 from both sides (-5-3). Finally, -5-3 is 8 because -5-3 is the same as -5+-3. When you add 5+3, you get 8. However, since your adding two negatives, you end up with -8. I hope this helped you!!!!!!

What is the exact value of the expression the square root of 20. + the square root of 24. - the square root 54.? simplify if pos

aksik [14]

$\sqrt{20} = \sqrt{4} \sqrt{5} = 2 \sqrt{5}$
$\sqrt{24} = \sqrt{4} \sqrt{6} = 2 \sqrt{6}$
$\sqrt{54} = \sqrt{9} \sqrt{6} = 3 \sqrt{6}$

Because you can only add and subtract radicals with the same radicand,
you get 2 $\sqrt{5} - \sqrt{6}$
that is the simplified answer but if you want it in decimals, 2.022 is what you get.

What is the value of p?<br> 10p+5 = 18p-6over 2

MAVERICK [17]

1) we have to subtract by the number 18p from each of your sides
Like: 10p + 5 - 18p
= 18p -3 -180
This gives us: -8p + 5 = -3
Nextly, we have to subtract by 5 on each of your sides
Like: -8p + 5 - 5
= -3 - 5
This gives us: -8p = -8
Now we have divide by the -8 on each of your sides:
Like: -8p ÷ -8
= -8 ÷ -8
Answer: p = 1

I hope it helped you:)
