Question

-4 а + 12 а + 13 А-27 A=​

Answer 1

-4а + 12а + 13а -27а=​ -6а

Answer 2

To solve the equation, we need to combine like terms and then isolate the variable "а" or "A". First, let's combine the "а" terms and the "А" terms:

-4а + 12а + 13А - 27A = 0

Next, let's combine the "а" terms:

(12а - 4а) + 13А - 27A = 0

Simplifying the "а" terms:

8а + 13А - 27A = 0

Now, let's combine the "А" terms:

8а - 14A = 0

Now, to isolate "а," we can factor out the "а" from the first term:

а(8 - 14A) = 0

Now, we have two possible solutions:

1. "а" can be equal to 0: а = 0
2. The expression inside the parentheses can be equal to 0:

8 - 14A = 0

Subtract 8 from both sides:

-14A = -8

Divide by -14:

A = 8/14

Simplify the fraction:

A = 4/7

So, the solutions to the equation are:

а = 0 and A = 4/7.
