Question

-9(6х+1)=-45(2х+2,6)

Answer 1

-9 ( 6х + 1 ) = -45 ( 2х + 2,6 )

-54х - 9 = -90х - 117

-54х + 90х = -117 + 9

36х = -108

х = (-108) ÷ 36

х = -3.

Ответ : х = -3.

Answer 2

To solve the equation, we'll first simplify both sides and then solve for the value of 'x'.

Let's start by simplifying the equation step by step:

1. Distribute the coefficients on the left side: -9(6x + 1) = -54x - 9

2. Distribute the coefficients on the right side: -45(2x + 2.6) = -90x - 117

Now, the equation becomes:

-54x - 9 = -90x - 117

Next, we want to isolate 'x' on one side of the equation. Let's move the 'x' terms to the left side and the constant terms to the right side:

Subtract -54x from both sides: -54x - (-90x) - 9 = -90x - (-90x) - 117

Simplify the equation: -54x + 90x - 9 = 0 - 117

Combine like terms: 36x - 9 = -117

Now, let's move the constant term (-9) to the right side by adding 9 to both sides:

36x - 9 + 9 = -117 + 9

Simplify the equation: 36x = -108

Finally, to solve for 'x', divide both sides by 36:

x = -108 / 36 x = -3

Therefore, the solution to the equation is x = -3.
