Question

2(x+5)<2 - 2x3(2-x) =3 -x​

Answer 1

Ответ:

Пошаговое объяснение:

$1)2(x+5)$

$2)3(2-x)=3-x\\6-3x=3-x\\-3x+x=3-6\\-2x=-3\\x=\frac{-3}{-2} \\x =1,5\\\\Proverka:\\3(2-1,5)=3-1,5\\6-4,5=1,5\\1,5=1,5$

Answer 2

Ответ:

2(x+5)<2-2x

сначала раскроем скобки.

2x+10<2-2x

теперь известные в одну сторону и другие в другую.

2x+2x<2-10

4x<-8

x<-2

2) 3(2-x)=3-x

6-3x=3-x

-3x+x=3-6

-2x=-3

x=1,5

Answer 3

It seems like you have an equation with inequalities and expressions that you'd like to solve. Let's break it down step by step and solve for x:

1. Start with the first inequality: 2(x + 5) < 2 - 2x

   First, distribute the 2 on the left side: 2x + 10 < 2 - 2x

   Now, move all the terms involving x to one side of the inequality, and constants to the other side: 2x + 2x + 10 - 2 < 2 - 2x - 2x

   This simplifies to: 4x + 10 - 2 < 2 - 4x

   4x - 2x is 2x, and 10 - 2 is 8, so you get: 2x + 8 < 2 - 4x

2. Now, solve for x:

   Start by isolating the x terms on one side of the inequality and the constants on the other side:

   2x + 4x < 2 - 8

   This simplifies to: 6x < -6

3. Finally, solve for x by dividing both sides by 6:

   (6x)/6 < (-6)/6

   This simplifies to: x < -1

So the solution for the first inequality is: x < -1.

Now, let's solve the second equation:

3 - x

There's no inequality in this equation, so it's just a linear expression. There's no need to solve it further; it's already in its simplest form:

3 - x

So, the solution to the second equation is simply 3 - x.

To summarize:

1. The solution to the first inequality is x < -1.
2. The solution to the second equation is 3 - x.
