Question

7х+2,4=34,6 (Х-1,8):7=1,2

Answer 1

Ответ:

Пошаговое объяснение:

7x=34.6-2.4

7x=32.2

x=32.2/7

x=4.6

x-1.8=1.2*7

x-1.8=8.4

x=8.4+1.8

x=10.2

Answer 2

To solve the equation, let's follow these steps:

Step 1: Simplify the expression inside the parentheses on the right side of the second equation. Step 2: Solve for x in the second equation. Step 3: Substitute the value of x into the first equation to find its value.

Let's start with Step 1:

(Х - 1.8) ÷ 7 = 1.2

Step 2: Simplify the expression inside the parentheses:

Х - 1.8 = 1.2 * 7

Х - 1.8 = 8.4

Step 3: Solve for x:

Х = 8.4 + 1.8

Х = 10.2

Now that we have the value of x, let's substitute it into the first equation:

7x + 2.4 = 34.6

7 * 10.2 + 2.4 = 34.6

71.4 + 2.4 = 34.6

73.8 = 34.6

This equation is not true, which means there is an error in the given equations or calculations. Please double-check the original equations or provide additional context if needed.
