Question

-9(6x+1)=-45×(2x+2,6)

Answer 1

Відповідь:

x = -3

Покрокове пояснення:

-9(6x + 1)= -45×(2x + 2,6)

-54x - 9 = -90x - 117

90x - 54x = 9 - 117

36x = -108

x = -108 : 36

x = -3

Answer 2

-9(6x+1)=-45(2x+2,6)
-54-9=-90x-117
90x=-117+54+9
90x=-54
x=-0,6

Answer 3

To solve the equation, let's first simplify it step by step:

Given equation: -9(6x+1) = -45 × (2x+2.6)

Step 1: Simplify both sides of the equation.

-9(6x+1) = -45 × (2x+2.6)

First, simplify the left side:

-9(6x+1) = -54x - 9

Now simplify the right side:

-45 × (2x+2.6) = -90x - 117

So the equation becomes:

-54x - 9 = -90x - 117

Step 2: Now, solve for x.

To do this, we need to isolate the x term. Let's move all the terms with x to one side and the constant terms to the other side.

First, add 90x to both sides:

-54x + 90x - 9 = -90x + 90x - 117

Simplify the equation:

36x - 9 = -117

Next, add 9 to both sides:

36x - 9 + 9 = -117 + 9

Simplify further:

36x = -108

Now, divide both sides by 36 to solve for x:

$x = -108/36 = -3$

So the solution for the equation is $x = -3$.
