Question

3 x−8 (2 x+5 )+(2 x−3 )=−10;

Answer 1

Ответ:

3 x−8 (2 x+5 )+(2 x−3 )=−10;

− x + 10 = 2 ( x + 3 ) − 8

− x + 10 = 2 x − 2

− 3 x + 10 = − 2

− 3 x = − 12

x = 4

 

Answer 2

To solve the equation $3x - 8(2x + 5) + (2x - 3) = -10$, we can follow these steps:

1. Distribute the constants outside the parentheses:

   $3x - 16x - 40 + 2x - 3 = -10$

2. Combine like terms on the left side of the equation:

   $-11x - 43 = -10$

3. Add 43 to both sides of the equation to isolate the term with $x$:

   $-11x = 33$

4. Divide both sides by -11 to solve for $x$:

   $x = -3$

So, the solution to the equation is $x = -3$.
