Question

2(3x+5)-3(4x-1)=11,8​

Answer 1

Ответ:

2(3x+5)-3(4x-1)=11,8

6x+10-12x+3=11,8

-6x+13=11,8

-6x=11,8-13

-6x= -1,2 |÷(-6)

x=0,2

Answer 2

To solve the equation 2(3x+5) - 3(4x-1) = 11.8, you'll need to simplify and then isolate the variable x. Here's how you can do it step by step:

1. Distribute the constants on the left side of the equation to their respective terms within the parentheses:

2(3x) + 2(5) - 3(4x) - 3(-1) = 11.8

2. Multiply the terms within the parentheses:

6x + 10 - 12x + 3 = 11.8

3. Combine like terms by adding or subtracting:

(6x - 12x) + (10 + 3) = 11.8

-6x + 13 = 11.8

4. Now, isolate the variable x. First, subtract 13 from both sides of the equation:

-6x + 13 - 13 = 11.8 - 13

-6x = -1.2

5. Finally, divide both sides by -6 to solve for x:

(-6x) / (-6) = (-1.2) / (-6)

x = 0.2

So, the solution to the equation 2(3x+5) - 3(4x-1) = 11.8 is x = 0.2.
