Question

1)-3,6(6х+1)=9(4-2х) Решите уравнение

Answer 1

-3,6(6x+1)=9(4-2x)

-21,6x-3,6=36-18x

-21,6x+18x=3,6+36

-3,6x=39,6

x=39,6:(-3,6)

x=-11

Answer 2

-21,6x-3,6=36-18x

-21,6x+18x=36+3,6

-3,6x=39,6

x=-(39,6/3,6)

x=-11

Answer 3

To solve the equation, let's first distribute the numbers outside the parentheses:

1 * (-3) + 6 * (6x + 1) = 9 * (4 - 2x)

Now, simplify both sides step by step:

-3 + 6x + 6 = 36 - 18x

Next, combine like terms on each side of the equation:

6x + 3 = 36 - 18x

To solve for x, we need to get all the x terms on one side and the constant terms on the other side. Let's add 18x to both sides of the equation:

6x + 3 + 18x = 36 - 18x + 18x

This simplifies to:

24x + 3 = 36

Now, let's isolate the term with x by subtracting 3 from both sides:

24x + 3 - 3 = 36 - 3

This simplifies to:

24x = 33

Finally, to find the value of x, divide both sides by 24:

x = 33 / 24

Now, if possible, simplify the fraction:

x = 11/8

So, the solution to the equation is:

x = 11/8 or x = 1.375 (as a decimal)
