Question

(7а + 1) + (6а+3)=5 СРОЧНО

Answer 1

Ответ:

(7а+1)+(6а+3)=5

7а+6а+1+3=5

13а=5-3-1

13а=1

а=1:13

а=1/13

_____________

(7*1/13+1)+(6*1/13+3)=7/13+1+6/13+3=13/13+1+3=1+1+3=5

Пошаговое объяснение:

Answer 2

$(7a + 1) + (6a + 3) = 5 \\ 7a + 1 + 6a + 3 = 5 \\ 7a + 6a = 5 - 1 - 3 \\ 13a = 1 \\ \boldsymbol{ a = \frac{1}{13} }$

Answer 3

To solve the equation, combine like terms first:

(7a + 1) + (6a + 3) = 5

Combine the terms with 'a':

7a + 6a = 13a

Combine the constant terms:

1 + 3 = 4

The equation now becomes:

13a + 4 = 5

Now, isolate the variable 'a' by subtracting 4 from both sides:

13a = 5 - 4 13a = 1

Finally, solve for 'a' by dividing both sides by 13:

a = 1/13

So the solution for the equation (7a + 1) + (6a + 3) = 5 is a = 1/13.
