Question

4(3/5х-3/10)-3×(7/10-1/10)=0 Помогите решить плис

Answer 1

Сначала раскрываем скобки,умножая то что за скобкой на каждый член в скобке,во второй скобке вычисляем значение 7/10-1/10=6/10, при одинаковых знаменателях числители просто отнимаем.

Так же,в ходе уравнения сократили такие дроби как 12/10 на 2,получили 6/5

При общ знаменателе равном 5 ,число 3 станет 15

Пошаговое объяснение:

4(3/5х-3/10)-3(7/10-1/10)=0

4×3/5x-4×3/10-3×6/10=0

12/5x-12/10-3×3/5=0

12/5x-12/10-9/5=0

12/5x-6/5-9/5=0

12/5x-3=0 /×5

12x-15=0

12x=15

x=15÷12

x=1,25

Answer 2

Solving the Equation

To solve the equation 4(3/5x - 3/10) - 3 × (7/10 - 1/10) = 0, we can follow these steps:

1. Simplify the terms inside the parentheses. 2. Perform the operations outside the parentheses. 3. Solve for the variable x.

Step 1: Simplify the Terms Inside the Parentheses

First, let's simplify the terms inside the parentheses:

4(3/5x - 3/10) - 3 × (7/10 - 1/10) = 0 = 4(3/5x - 3/10) - 3 × (6/10)

Step 2: Perform the Operations Outside the Parentheses

Now, we can perform the operations outside the parentheses:

= 4(3/5x - 3/10) - 18/10 = 12/5x - 12/10 - 18/10 = 12/5x - 30/10 = 12/5x - 3

Step 3: Solve for the Variable x

Now, we can set the expression equal to 0 and solve for x:

12/5x - 3 = 0 12/5x = 3 x = 3 * 5 / 12 x = 5/4

Final Answer

So, the solution to the equation 4(3/5x - 3/10) - 3 × (7/10 - 1/10) = 0 is x = 5/4.
