Question

2,1x-3(2,5x+3,6)=10,4x-7,64 плиз​

Answer 1

Ответ:

x=0,2

Пошаговое объяснение:

2,1x-3(2,5x+3,6)=10,4x-7,64

2,1x-7,5x-10,8=10,4x-7,64

-5,4x-10,8=10,4x-7,64

-10,8+7,64=10,4x+5,4x

-3,16=15,8x

x=-0,2

Answer 2

Sure, I can help you solve the equation. Let's start by simplifying the equation step by step.

2.1x - 3(2.5x + 3.6) = 10.4x - 7.64

Step 1: Distribute the -3 on the left side:

2.1x - 3 * 2.5x - 3 * 3.6 = 10.4x - 7.64

Step 2: Simplify the terms:

2.1x - 7.5x - 10.8 = 10.4x - 7.64

Step 3: Combine the x terms on the left side:

(2.1x - 7.5x) - 10.8 = 10.4x - 7.64

-5.4x - 10.8 = 10.4x - 7.64

Step 4: Move the x terms to one side of the equation:

-5.4x - 10.4x = -7.64 + 10.8

-15.8x = 3.16

Step 5: Solve for x by dividing both sides by -15.8:

x = 3.16 / -15.8

x = -0.2

So, the solution to the equation is x = -0.2.
