Answer 1

Ответ:

Пошаговое объяснение:

0,6х+4,2-0,5х+1,5=6,8

0,6х-0,5х=6,8-1,5-4,2

0,1х=1,1

Х=1,1:0,1

Х=11

Answer 2

Ответ:

Пошаговое объяснение:0,6x+4,2-0,5x+1,5=6,8

0,1x=1,1

x=1,1/0,1

x=11

Answer 3

To solve the equation, follow these steps:

Step 1: Distribute the coefficients to eliminate the parentheses. Step 2: Combine like terms on both sides of the equation. Step 3: Isolate the variable (x) on one side of the equation. Step 4: Solve for x.

Let's proceed with the steps:

Step 1: Distribute the coefficients.

0.6 * (x + 7) - 0.5 * (x - 3) = 6.8

Multiply the coefficients with the terms inside the parentheses:

0.6x + 4.2 - 0.5x + 1.5 = 6.8

Step 2: Combine like terms.

Now, combine the terms that have 'x':

(0.6x - 0.5x) + (4.2 + 1.5) = 6.8

0.1x + 5.7 = 6.8

Step 3: Isolate the variable (x).

Subtract 5.7 from both sides of the equation to move the constant term to the other side:

0.1x = 6.8 - 5.7

0.1x = 1.1

Step 4: Solve for x.

To solve for x, divide both sides by 0.1:

x = 1.1 / 0.1

x = 11

Therefore, the solution to the equation is x = 11.
