Answer 1

12 - а - 56 = 43
-44 -a = 43
a = -44-43
a = -87

Answer 2

To solve the equation 12 - a - 56 = 43, we need to isolate the variable 'a' on one side of the equation.

First, we can simplify the left-hand side by combining the constants:

12 - a - 56 = -44 - a

Now we can add 44 to both sides to get:

-a = 43 + 44

Simplifying the right-hand side:

-a = 87

Finally, we can solve for 'a' by multiplying both sides by -1:

a = -87

Therefore, the solution to the equation 12 - a - 56 = 43 is a = -87.
