Question

-2(x+5)-(5-x)=5x+(10-x)

Answer 1

Ответ:

х= -5

Пошаговое объяснение:

-2(х+5) - (5-х)= 5х+(10-х)

-2х - 10 -5+х=5х+10-х

-х-15=4х+10

-5х=25

х = -5

Answer 2

Let's solve the equation step by step:

1. Expand the expressions on both sides of the equation:

-2(x + 5) - (5 - x) = 5x + (10 - x)

2. Apply the distributive property (distributing the -2 and the -1):

-2x - 10 - 5 + x = 5x + 10 - x

3. Combine like terms on both sides:

-2x + x - 10 - 5 = 5x - x + 10

4. Simplify:

-x - 15 = 4x + 10

5. Now, let's get all the x terms on one side and the constants on the other side:

Add x to both sides:

-x + x - 15 = 4x + x + 10

Simplify:

-15 = 5x + 10

6. Next, subtract 10 from both sides:

-15 - 10 = 5x + 10 - 10

Simplify:

-25 = 5x

7. Finally, divide both sides by 5 to isolate x:

x = -25 / 5

Simplify:

x = -5

So, the value of x that satisfies the equation is x = -5. You can verify this by substituting -5 for x in the original equation and checking if both sides are equal.
