Question

Решите (1.2х-х)*0.5-0.3=1

Answer 1

$(1.2x-x)*0.5-0.3=1\\0.2x*0.5-0.3=1\\0.1x-0.3=1\\0.1x=1+0.3\\0.1x=1.3\\x=1.3*0.1\\x=13$

Answer 2

(1,2х - х) * 0,5 - 0,3 = 1
0,2х * 0,5 - 0,3 = 1
0,2х * 0,5 = 1 + 0,3
0,2х * 0,5 = 1,3
0,2х = 1,3 : 0,5
0,2х = 2,6
х = 2,6 : 0,2
х = 13
Проверка:
(1,2 * 13 - 13) * 0,5 - 0,3 = 1
(15,6 - 13) * 0,5 - 0,3 = 1
2,6 * 0,5 - 0,3 = 1
1,3 - 0,3 = 1
1=1
Ответ: х = 13

Answer 3

To solve the equation (1.2x - x) * 0.5 - 0.3 = 1, we can follow these steps:

Step 1: Simplify the equation First, let's simplify the equation by combining like terms.

(1.2x - x) * 0.5 - 0.3 = 1

The expression (1.2x - x) simplifies to 0.2x. So, the equation becomes:

0.2x * 0.5 - 0.3 = 1

Step 2: Simplify further Now, let's simplify the left side of the equation.

0.2x * 0.5 - 0.3 = 1

0.1x - 0.3 = 1

Step 3: Isolate the variable Next, let's isolate the variable x by moving the constant term (-0.3) to the other side of the equation.

0.1x - 0.3 + 0.3 = 1 + 0.3

0.1x = 1.3

Step 4: Solve for x To solve for x, divide both sides of the equation by 0.1.

(0.1x) / 0.1 = 1.3 / 0.1

x = 13

So, the solution to the equation (1.2x - x) * 0.5 - 0.3 = 1 is x = 13.
