x = 6

Explanation:

The distributive property is shown here:

Although the image has two terms inside the parenthesis rather than three terms in the question, we can apply it to this question.

The color(blue)2 multiplies to everything inside the parenthesis:
(2 * x) + (2 * -5) + (2 * 2) = 6

Now simplify by multiplying:
2x - 10 + 4 = 6

Combine color(blue)(-10 + 4):
2x - 6 = 6

Add color(blue)6 to both sides:
2x - 6 quadcolor(blue)(+quad6) = 6 quadcolor(blue)(+quad6)

2x = 12

Divide both sides by color(blue)2
(2x)/color(blue)2 = 12/color(blue)2

x = 6

Hope this helps!

x=6

Explanation:

Since the 2 is outside the parentheses, that is the number that is going to be distributed. You'll multiply 2 by x, 2 by -5, and then 2 by 2. Therefore, you should get 2x, -10, and 4.

Put those together and you have your new equation:

2x-10+4=6

Now, you can add -10 and 4 to get -6, so your equation will be

2x-6=6

Add 6 to both sides. Then you'll get the equation

2x=12

Now you have a division by 2 on both sides to get your answer that

x=6

x = 6

Explanation:

Distributive Property is when you get rid of the brackets so what happens is...

You got the equation...
color(red)(2(x - 5 + 2)) = color(blue)(6)
You take the one with brackets...
color(red)(2(x - 5 + 2))
Then you times the number outside the brackets with everything inside like this...
color(red)(2)color(blue)((x - 5 + 2)

color(red)(2) xx color(blue)x = 2x
color(red)2 xx color(blue)(-5) = -10
color(red)2 xx color(blue)(2)= 4

2x - 10 + 4

so color(red)(2(x - 5 + 2)) becomes color(red)(2x - 10 + 4)

Now you got: 2x - 10 + 4 = 6
With this, you can now find the 'color(green)(x)'

color(orange)(2x - 10 + 4 = 6
2x color(red)(- 10 + 4) = 6
adding the together...
2x color(red)(- 6) = 6

color(orange)(2x - 6 = 6
2x color(red)(- 6) = color(red)(6
moving -6 to the other side...
2x = color(red)(6) color(red)(+ 6
2x = color(red)(12

color(orange)(2x = 12
color(red)(2)x = color(red)(12
moving 2 to the other side...
x = color(red)(12)/color(red)(2 (12 divided by 2)
x = color(red)(6)
