Answer 1

Ответ:

Пошаговое объяснение:

-11а = 11/3 - 11

-11а = (-22/3)

а = 2/3

Answer 2

$- 11a = \frac{11}{3} - 11 \\ - 11a = - \frac{22}{3} \\ a = \frac{2}{3}$

Answer 3

To solve the equation -11a = 11/3 - 11, we'll follow these steps:

Step 1: Simplify the right-hand side of the equation. Step 2: Isolate the variable 'a' on one side of the equation.

Let's begin:

Step 1: To simplify the right-hand side, we need to find a common denominator for 11/3 and 11. The common denominator is 3.

11/3 can be rewritten as (11/3) * (3/3) = 33/9. 11 remains the same since it is already over the common denominator.

So, the equation becomes:

-11a = 33/9 - 11

Step 2: Next, let's isolate the variable 'a' on one side of the equation. We want to get rid of the constant term first by subtracting 33/9 from both sides:

-11a - 33/9 = -11 - 33/9

To simplify the right-hand side further, find the common denominator for -11 and 33/9. The common denominator is 9.

-11 can be rewritten as (-11) * (9/9) = -99/9. 33/9 remains the same.

So, the equation becomes:

-11a - 33/9 = -99/9 - 33/9

Now, combine the fractions on the right-hand side:

-11a - 33/9 = (-99 - 33)/9 = -132/9

Step 3: Now, we want to get rid of the fraction on the left-hand side by multiplying both sides by -9 (to eliminate the fraction 1/9):

-9 * (-11a - 33/9) = -9 * (-132/9)

Simplify both sides:

99a + 33 = 132

Step 4: Finally, isolate the variable 'a' by subtracting 33 from both sides:

99a + 33 - 33 = 132 - 33

Simplify:

99a = 99

Step 5: To solve for 'a', divide both sides by 99:

a = 99/99

Simplify further:

a = 1

So, the solution to the equation is a = 1.
