Question

2(х+2) -4(х+1) =5х+9

Answer 1

Ответ:

2(х+2) -4(х+1) =5х+9

2х+4 - 4х-4=5х+9

2х-4х-5х=9-4+4

-7х=9

-х=9/7

х= - 1 2/7

Answer 2

Let's solve the given equation step by step:

2(x + 2) - 4(x + 1) = 5x + 9

First, we need to distribute the multiplication:

2x + 4 - 4x - 4 = 5x + 9

Combine like terms:

(2x - 4x) + (4 - 4) = 5x + 9

-2x + 0 = 5x + 9

Simplify further:

-2x = 5x + 9

Now, let's isolate the x terms on one side of the equation:

-2x - 5x = 9

-7x = 9

Divide both sides of the equation by -7 to solve for x:

x = 9 / -7

Simplifying the fraction:

x = -9/7

So, the solution to the equation is x = -9/7.
