Question

8 x -3 ( 2 X - 3)= 7х-2(5х+8)​

Answer 1

Ответ:

8x - 6x + 9 = 7x - 10x - 16

8x - 6x - 7x + 10x = - 16 - 9

5x = - 25

x = -25/5

x = -5

Объяснение:

для начала нужно убрать скобки, умножаем число за скобкой (-3 и -2), далее переносим все x влево, остальные числа вправо, дальше отнимаем и прибавляем

Answer 2

Ответ:

x = - 5

Объяснение:

Справка:

• если перед скобкой стоит множитель, то каждый член скобки умножается на него ;
• "минус" на "плюс" и "плюс" на "минус" всегда дают в итоге "минус" ;
• "минус" на "минус" и "плюс" на "плюс" всегда дают в итоге "плюс" .

Решение:

8x - 3(2x - 3) = 7x - 2(5x + 8)

8x - 6x + 9 = 7x - 10x - 16

2x + 3x = - (9 + 16)

5x = - 25

x = - 25 : 5

x = - 5

Answer 3

Let's simplify each expression step by step:

1. Simplify the left-hand side (LHS) expression: 8x - 3(2x - 3)

To simplify, apply the distributive property (also known as the FOIL method): 8x - 3(2x) - 3(-3) 8x - 6x + 9

Now combine like terms: (8x - 6x) + 9 2x + 9

So the simplified left-hand side expression is 2x + 9.

2. Simplify the right-hand side (RHS) expression: 7x - 2(5x + 8)

Apply the distributive property again: 7x - 2(5x) - 2(8) 7x - 10x - 16

Now combine like terms: (7x - 10x) - 16 -3x - 16

So the simplified right-hand side expression is -3x - 16.

Now we have: LHS: 2x + 9 RHS: -3x - 16

The equation to solve is: 2x + 9 = -3x - 16

To solve for x, we need to get all the x terms on one side and the constant terms on the other side. Let's do that:

Add 3x to both sides: 2x + 3x + 9 = -3x + 3x - 16

Combine like terms: 5x + 9 = -16

Now, subtract 9 from both sides to isolate the x term: 5x + 9 - 9 = -16 - 9

Simplify: 5x = -25

Finally, to find the value of x, divide both sides by 5: x = -25 / 5

x = -5

So the solution to the equation is x = -5.
