Question

1,2x +.4,1 = 18,5 уравнение ​

Answer 1

Ответ:

Пошаговое объяснение:

1,2х=18,5-4,1

1,2х=14,4

Х=14,4:1,2

Х=12

Answer 2

1,2х - 4,1 = 18,5

1,2х = 18,5 - 4,1

1,2х = 14,4

х = 14,4 : 1,2

х = 12

Answer 3

It seems there is a slight error in the formatting of the equation you provided. I'll assume that you meant to write the equation as follows:

1.2x + 0.4 = 18.5

To solve for x, follow these steps:

Step 1: Subtract 0.4 from both sides to isolate the term with x on the left side of the equation.

1.2x + 0.4 - 0.4 = 18.5 - 0.4

1.2x = 18.1

Step 2: Divide both sides by 1.2 to solve for x.

x = 18.1 / 1.2

x ≈ 15.08

So, the value of x that satisfies the equation is approximately 15.08.
