Question

8 4/25 - (х + 3 21/25) = 2 19/25

Answer 1

Ответ:

Пошаговое объяснение:

8 4/25 - (х + 3 21/25) = 2 19/25

8 4/25 - х - 3 21/25 = 2 19/25

4 8/25 - x = 2 19/25

x = 4 8/25 - 2 19/25

x = 1 14/25

Answer 2

To solve the equation, let's convert all the mixed numbers to improper fractions:

8 4/25 = (8 * 25 + 4) / 25 = 204/25 2 19/25 = (2 * 25 + 19) / 25 = 69/25

The equation becomes:

204/25 - (x + 3 21/25) = 69/25

Now, let's simplify the equation by adding the whole numbers and fractions separately:

204/25 - (x + 3 21/25) = 69/25 204/25 - (x + 96/25) = 69/25

To simplify further, let's remove the parentheses:

204/25 - x - 96/25 = 69/25

Now, let's combine like terms on the left side:

(204/25 - 96/25) - x = 69/25 (204 - 96)/25 - x = 69/25 108/25 - x = 69/25

To isolate the variable x, let's subtract 108/25 from both sides:

(108/25 - x) - 108/25 = (69/25 - 108/25)

• x = -39/25

Finally, let's solve for x by multiplying both sides by -1:

-1 * (-x) = -1 * (-39/25) x = 39/25

Therefore, the solution to the equation is x = 39/25.
