Answer 2

1. (5.6 - x) + 3.8 = 4.4

To solve this equation, we will isolate the variable x by performing the necessary operations.

First, let's simplify the equation:

5.6 - x + 3.8 = 4.4

Combine like terms:

9.4 - x = 4.4

Next, let's isolate x by moving 9.4 to the other side of the equation:

-x = 4.4 - 9.4

Simplify:

-x = -5

Now, multiply both sides of the equation by -1 to solve for x:

x = -(-5)

x = 5

So the solution to the equation is x = 5.

2. (12/m) - 0.2 = 3.8

To solve this equation, we will isolate the variable m.

First, let's simplify the equation:

(12/m) - 0.2 = 3.8

Next, let's isolate (12/m) by moving -0.2 to the other side of the equation:

12/m = 3.8 + 0.2

Simplify:

12/m = 4

Now, cross-multiply:

12 = 4m

Divide both sides of the equation by 4 to solve for m:

12/4 = m

3 = m

So the solution to the equation is m = 3.

3. (x - 5.4) + 2.3 = 5.2

To solve this equation, we will isolate the variable x.

First, let's simplify the equation:

(x - 5.4) + 2.3 = 5.2

Next, let's combine like terms:

x - 5.4 + 2.3 = 5.2

Combine the constants:

x - 3.1 = 5.2

Next, let's isolate x by moving -3.1 to the other side of the equation:

x = 5.2 + 3.1

Simplify:

x = 8.3

So the solution to the equation is x = 8.3.
