Answer 2

5780-a=665:7
5780-a=95
a=5780-95
a=5685

Answer 3

Let's solve the equation step by step.

First equation: 5,780 - a = 665

To find the value of 'a', we need to isolate 'a' on one side of the equation. We can do this by subtracting 665 from both sides:

5,780 - a - 665 = 665 - 665

This simplifies to:

5,115 - a = 0

Now, to isolate 'a', we can subtract 5,115 from both sides:

5,115 - a - 5,115 = 0 - 5,115

This simplifies to:

-a = -5,115

Multiplying both sides by -1 to solve for 'a':

a = 5,115

So the value of 'a' in the first equation is 5,115.

Second equation: 75,780 - a = ? (we'll solve for '?')

We already found that 'a' is equal to 5,115, so we can substitute it into the equation:

75,780 - 5,115 = ?

Calculating the subtraction:

70,665 = ?

Therefore, in the second equation, the value of '?' is 70,665.
