(15+71)2=-526-12+710

Answer 2

It appears that you've provided a set of equations with some missing numbers represented by dots. You'd like me to fill in the missing numbers. Let's solve each equation one by one:

1. ...:7=12...+27....

Let's solve for the missing number on the left side of the equation: .../7 = 12... + 27....

To find the missing number on the left side, let's first solve for the right side:

12... + 27 = 12... + 27

Now, let's isolate the missing number:

12... = 12... + 27 - 27

12... = 12...

It seems that both sides of the equation are equal, which means there can be multiple solutions for the missing number. It could be any number since any number divided by itself is 1. So, the left side could be any number.

2. (15+71)....=...-12+71....

Let's solve for the missing number on the left side of the equation: (15 + 71).... = ... - 12 + 71....

First, calculate the left side:

(15 + 71).... = 86....

Now, let's isolate the missing number on the right side:

86.... = ... - 12 + 71....

To find the missing number on the right side:

86.... = ... + 59

Now, subtract 59 from both sides to solve for the missing number:

86.... - 59 = ...

The missing number on the right side is 27.

So, the equation is:

86.... = 27

3. ...-13=23....-16:...

Let's solve for the missing number on the left side of the equation: ... - 13 = 23.... - 16:...

First, calculate the left side:

... - 13 = ... - 16:...

Now, let's isolate the missing number on the right side:

... - 13 = ... - 16:...

Both sides of the equation are the same, so there can be multiple solutions for the missing number. It could be any number since any number minus itself is 0. So, the missing number on both sides could be any number.

4. 63-... = ...-51-....28

Let's solve for the missing number on the left side of the equation: 63 - ... = ... - 51 - ....28

First, calculate the right side:

... - 51 - ....28 = ... - 79

Now, let's isolate the missing number on the left side:

63 - ... = ... - 79

Add ... to both sides to solve for the missing number:

63 = ... - 79 + ...

Now, subtract 79 from both sides:

63 = ...

The missing number on the left side is 63.

So, the equation is:

63 - 63 = ... - 79

Now, you can calculate the missing number on the right side:

0 = ... - 79

Add 79 to both sides:

79 = ...

The missing number on the right side is 79.

So, the equation is:

63 - 63 = 79 - 79

Which simplifies to:

0 = 0

I hope this helps! If you have any more equations or questions, please feel free to ask.
