Question

8 x -3 (2x - 3) = 7х-2(5х+8)​

Answer 1

Ответ:

x = - 5

Пошаговое 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 в итоге дают "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 2

To solve the equation, we'll start by simplifying both sides step by step.

Given equation: 8x - 3(2x - 3) = 7x - 2(5x + 8)

Step 1: Distribute the terms inside the parentheses. 8x - 6x + 9 = 7x - 10x - 16

Step 2: Combine like terms on both sides. (8x - 6x) + 9 = (7x - 10x) - 16

Step 3: Simplify further. 2x + 9 = -3x - 16

Step 4: Move all the x terms to one side and the constant terms to the other side. 2x + 3x = -16 - 9

Step 5: Combine like terms. 5x = -25

Step 6: Solve for x by dividing both sides by 5. x = -25 / 5

Step 7: Simplify the result. x = -5

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