Question

-2 (x+3) =x 3•(2-s)=2s-(s+6)

Answer 1

Пошаговое объяснение:

-2(х + 3) = х

-2х - 6 = х

-2х - х = 6

-3х = 6

х = 6 : (-3)

х = -2

3(2 - s) = 2s - (s + 6)

6 - 3s = 2s - s - 6

6 - 3s = s - 6

-3s - s = -6 - 6

-4s = -12

s = -12 : (-4)

s = 3

Answer 2

To solve the equations:

1. -2(x + 3) = x

Let's simplify the equation by distributing the -2 on the left side:

-2x - 6 = x

Now, let's isolate x by moving the x terms to one side and the constants to the other side:

-2x - x = 6

Combine like terms:

-3x = 6

Now, divide both sides by -3 to solve for x:

x = 6 / (-3)

x = -2

So, the solution to the first equation is x = -2.

2. 3(2 - s) = 2s - (s + 6)

Let's simplify the equation step by step:

First, distribute the 3 on the left side:

6 - 3s = 2s - (s + 6)

Now, let's simplify the right side by removing the parentheses:

6 - 3s = 2s - s - 6

Combine like terms on the right side:

6 - 3s = s - 6

Next, let's move all the s terms to one side and constants to the other side:

6 + 6 = s + 3s

Combine like terms:

12 = 4s

Now, divide both sides by 4 to solve for s:

s = 12 / 4

s = 3

So, the solution to the second equation is s = 3.

To summarize:

1. x = -2
2. s = 3
