Question

(x-3 13/21)+2 10/21=7 2/21 дайте ответ на уровнение

Answer 1

(x-3 13/21)+2 10/21=7 2/21
x-76\21+52\21 = 149\21
21x-76+52=149
21x=173
x=173\21

Answer 2

To solve the equation:

(x - 3 13/21) + 2 10/21 = 7 2/21

We need to isolate x on one side of the equation.

First, we can simplify the mixed numbers to improper fractions:

(x - 76/21) + 52/21 = 149/21

Then, we can combine the two fractions on the left-hand side:

x - 24/21 = 149/21 - 52/21

Next, we can simplify the right-hand side:

x - 24/21 = 97/21

To isolate x, we can add 24/21 to both sides:

x - 24/21 + 24/21 = 97/21 + 24/21

Simplifying both sides:

x = 121/21

Therefore, the solution to the equation is:

x = 121/21 or x = 5 16/21
