Question

-5x-5+5(x-5)=-(-5-x)-4 СРОЧНЯК!!

Answer 1

Ответ:

x = -31

Пошаговое объяснение:

-5*x-5+5*(x-5) = -(-5-x)-4

-5*x-5+5*x-5*5 = -(-5-x)-4

-5*x-5+5*x-5*5 = 5+x-4

-30 = 5+x-4

-30 = 1 + x

0 = x + 31

-x = 31

x = 31 / (-1)

Answer 2

Ответ:

х= -31

Пошаговое объяснение:

Раскрываем скобки:

-5х - 5 + 5 х - 25 = 5 + х - 4

-5 х + 5 х - х = 5 -4+5+25

-х = 31

х = - 31

Answer 3

Let's solve the equation step by step:

-5x - 5 + 5(x - 5) = -(-5 - x) - 4

Step 1: Distribute the 5 on the left side of the equation.

-5x - 5 + 5x - 25 = -(-5 - x) - 4

Step 2: Simplify the left side of the equation.

(-5x + 5x) - 5 - 25 = -(-5 - x) - 4

Step 3: Combine like terms.

0 - 30 = -(-5 - x) - 4

Step 4: Simplify further.

-30 = -(-5 - x) - 4

Step 5: Now, let's remove the double negative on the right side.

-30 = -(5 + x) - 4

Step 6: Remove the parenthesis on the right side.

-30 = -5 - x - 4

Step 7: Combine like terms on the right side.

-30 = -9 - x

Step 8: Finally, solve for x by isolating the x term on one side of the equation.

To get rid of the negative sign on the right side, we can multiply both sides by -1:

-1*(-30) = -1*(-9 - x)

30 = 9 + x

Step 9: Now, isolate the x term by subtracting 9 from both sides of the equation.

30 - 9 = x

x = 21

So, the value of x that satisfies the equation is x = 21.
