Question

-3 1/4 - x = 2,6 - 4,1​

Answer 1

Ответ:

3 1/3 - х = 2,6-4,1

3 1/3 - х = -1,5

х = 3 1/3 + 1,5

х = 10/3 + 15/10

х = 100/30+45/30

х = 145/30 =29/6 = 4 5/6= 4,83

Answer 2

Ответ:

$-3\frac{1}{4}-x=2,6-4,1\\-3,25-x=2,6-4,1\\-3,25-x= -1,5\\-x=-1,5+3,25\\-x=1,75\\x=-1,75\\-------------------\\-3,25-(-1,75)=2,6-4,1\\-3,25+1,75=-1,5\\-1,5=-1,5$

Answer 3

To solve the equation -3 1/4 - x = 2.6 - 4.1, follow these steps:

Step 1: Convert the mixed number -3 1/4 to an improper fraction.

-3 1/4 = -3 - 1/4 = -3 - 4/4 + 1/4 = -3 - 1 + 1/4 = -4 1/4

So, the equation becomes:

-4 1/4 - x = 2.6 - 4.1

Step 2: Subtract 4 1/4 from both sides of the equation to isolate x.

-4 1/4 - x + 4 1/4 = 2.6 - 4.1 + 4 1/4

On the left side, the -4 1/4 and 4 1/4 cancel out, leaving us with:

-x = 2.6 - 4.1 + 4 1/4

Step 3: Calculate the right side of the equation.

2.6 - 4.1 = -1.5

Now, add 4 1/4 to -1.5:

-1.5 + 4 1/4 = 2 3/4

So, the right side simplifies to 2 3/4.

Step 4: Substitute this value back into the equation:

-x = 2 3/4

Step 5: To isolate x, multiply both sides by -1 to change the sign of the equation:

-x * (-1) = 2 3/4 * (-1)

This simplifies to:

x = -2 3/4

So, the solution to the equation -3 1/4 - x = 2.6 - 4.1 is:

x = -2 3/4
