Question

Решите уравнение : 1) 7/12 (семь двенадцатых) +g=1 2)1-g=4/15 3)g+7/16=1 4)1-g=13/21

Answer 1

1) 7/12+g=1
Переносим числа без переменной вправо с противоположным знаком:
g=1-7/12=(12-7)/12=5/12
Ответ: g=5/12.

2) 1-g=4/15
-g=4/15-1=(4-15)/15=-11/15, g=11/15
Ответ: g=11/15.

3) g+7/16=1
g=1-7/16=(16-7)/16=9/16
Ответ: g=9/16.

4) 1-g=13/21
-g=13/21-1=(13-21)/21=-8/21, g=8/21
Ответ: g=8/21

Answer 2

1) = 5/12
2) = 11/15
3) = 9/16
4) = 8/21

Answer 3

Решение уравнений:

1) 7/12 * g = 1

To solve for g, we can multiply both sides of the equation by the reciprocal of 7/12, which is 12/7:

g = 1 * (12/7) g = 12/7

So the solution to the first equation is g = 12/7.

2) 1 - g = 4/15

To solve for g, we can subtract 1 from both sides of the equation:

-g = 4/15 - 1 -g = 4/15 - 15/15 -g = -11/15

Now, to solve for g, we can multiply both sides of the equation by -1:

g = 11/15

So the solution to the second equation is g = 11/15.

3) g + 7/16 = 1

To solve for g, we can subtract 7/16 from both sides of the equation:

g = 1 - 7/16 g = 16/16 - 7/16 g = 9/16

So the solution to the third equation is g = 9/16.

4) 1 - g = 13/21

To solve for g, we can subtract 1 from both sides of the equation:

-g = 13/21 - 1 -g = 13/21 - 21/21 -g = -8/21

Now, to solve for g, we can multiply both sides of the equation by -1:

g = 8/21

So the solution to the fourth equation is g = 8/21.

Therefore, the solutions to the given equations are: 1) g = 12/7 2) g = 11/15 3) g = 9/16 4) g = 8/21
