Question

8(3,5-1,5х)=35,5-1,5(7+2х)

Answer 1

Ответ:

1/3

Объяснение:

8(3,5 - 1,5х) = 35,5 - 1,5(7 + 2х)

28 - 12х = 35,5 - 10,5 - 3х

28 - 12х = 25 - 3х

-12х + 3х = 25 - 28

-9х = -3

х = -3 : (-9)

х = 3/9

х = 1/3

Answer 2

8 (3,5 - 1,5 x = 35,5 - 1,5\7 + 2x)

28-12 x= 35,5 - 10,5 - 3 x

28-12×= 25 -3x

-12 x+3x= 25-28

-9x=-3
x=1/3

Answer 3

Let's solve the equation step by step:

8(3.5 - 1.5x) = 35.5 - 1.5(7 + 2x)

First, distribute the 8 on the left side of the equation:

28 - 12x = 35.5 - 1.5(7 + 2x)

Now, distribute the -1.5 on the right side of the equation:

28 - 12x = 35.5 - 10.5 - 3x

Next, simplify the right side by combining like terms:

28 - 12x = 25 - 3x

Now, let's isolate the variables on one side of the equation and constants on the other side. Start by adding 12x to both sides to get the x terms on the left side:

28 - 12x + 12x = 25 - 3x + 12x

This simplifies to:

28 = 25 + 9x

Now, subtract 25 from both sides to isolate the 9x term:

28 - 25 = 25 - 25 + 9x

3 = 9x

Finally, divide both sides by 9 to solve for x:

3/9 = 9x/9

1/3 = x

So, the solution to the equation is:

x = 1/3
