Question

Б)1/2+х=1/4 А)-1,3+х=2,18

Answer 1

Ответ:

Пошаговое объяснение:

1/2+х=1/4

х = 1/4 -1/2 = 1/4 - 2/4

х = -1/4

-1,3+х=2,18

х = 2,18 + 1,3

х = 3,48

Answer 2

To solve the equations, let's go through them one by one:

Б) 1/2 + x = 1/4

To solve this equation, we need to isolate the variable x on one side of the equation.

First, let's get rid of the fractions by finding a common denominator, which in this case is 4:

1/2 + x = 1/4

Multiply both sides of the equation by 4:

4 * (1/2 + x) = 4 * (1/4)

This simplifies to:

2 + 4x = 1

Now, let's isolate x by moving the constant term to the other side:

4x = 1 - 2

4x = -1

Finally, divide both sides of the equation by 4:

x = -1/4

Therefore, the solution to the equation is x = -1/4.

A) -1.3 + x = 2.18

To solve this equation, we need to isolate the variable x on one side of the equation.

Let's start by moving the constant term to the other side:

x = 2.18 + 1.3

x = 3.48

Therefore, the solution to the equation is x = 3.48.
