Answer 1

Ответ:

39х-55

Объяснение:

Распределяем 4 через скобки: 20х-8-7(1-2х)-5(8-х)

Распределяем -7 через скобки: 20х-8-7+14х-5(8-х)

Распределяем -5 через скобки: 20х-8-7+14х-40+5х

Приводим подобные: 39х-55

Answer 2

Ответ:

4(5х-2)-7(1-2х)-5(8-х)=20х-8-7+14х-40+5х=39х-55

Answer 3

To simplify the given expression, you need to apply the distributive property (also known as the distributive law or the distributive property of multiplication over addition/subtraction). Here's how you can simplify the expression step by step:

Given expression: 4(5x - 2) - 7(1 - 2x) - 5(8 - x)

Step 1: Distribute the constants and variables inside the parentheses:

= 4 * 5x - 4 * 2 - 7 * 1 + 7 * 2x - 5 * 8 + 5 * x

Step 2: Perform the multiplications:

= 20x - 8 - 7 + 14x - 40 + 5x

Step 3: Combine like terms (terms with the same variable raised to the same power):

= (20x + 14x + 5x) + (-8 - 7 - 40)

Step 4: Simplify further:

= 39x - 55

So, the simplified expression is: 39x - 55
