Question

-2(х+4)=3х+2 .........​

Answer 1

Ответ:

-2(x + 4) = 3x + 2

-2x - 8 = 3x + 2

-8 - 2 = 3x + 2x

-10 = 5x

x = - 10 / 5

x = - 2

Answer 2

To solve the equation -2(x+4) = 3x+2, you can follow these steps:

1. Distribute the -2 on the left side of the equation to both terms inside the parentheses: -2x - 8 = 3x + 2

2. Move the variable terms (those with x) to one side and the constant terms to the other side of the equation. You can do this by adding 2x to both sides and adding 8 to both sides to isolate x:

-2x - 2x - 8 + 8 = 3x + 2 - 2x + 8

Simplify:

-4x = 3x + 10

3. Now, move the 3x term to the left side by subtracting 3x from both sides:

-4x - 3x = 3x - 3x + 10

Simplify:

-7x = 10

4. Finally, solve for x by dividing both sides by -7:

-7x / -7 = 10 / -7

x = -10/7

So, the solution to the equation is:

x = -10/7
