Answer 2

Ответ:

4х=0,275

Пошаговое объяснение:

30*2=60

60-10=50

50:7=7,1

7,1-6=1,1

1,1:4=0,275

Answer 3

To solve the equation ((4x + 6) * 7 - 10) : 2 = 30, we need to follow the order of operations (also known as PEMDAS/BODMAS).

Let's break it down step by step:

1. Simplify the expression within the parentheses: (4x + 6) * 7 - 10 Multiply the terms inside the parentheses by 7: 28x + 42 - 10

2. Combine like terms: 28x + 42 - 10 Simplify: 28x + 32

3. Divide the result by 2: (28x + 32) : 2 Simplify: 14x + 16

Now we have the equation: 14x + 16 = 30

To solve for x, we'll isolate the variable on one side of the equation:

1. Subtract 16 from both sides: 14x + 16 - 16 = 30 - 16 Simplify: 14x = 14

2. Divide both sides by 14 to solve for x: (14x) / 14 = 14 / 14 Simplify: x = 1

Therefore, the solution to the equation ((4x + 6) * 7 - 10) : 2 = 30 is x = 1.
