3+5+4=71

3+5+3=41
5+4+6=43
2+7+3=31
6+7+3=??

To find the value of 6+7+3, we can look for patterns in the given equations.

In the first equation, 3+5+4=71, if we add the first two numbers (3+5=8) and multiply it by the third number (8*4=32), we get 71.

In the second equation, 3+5+3=41, the pattern doesn't seem to hold. However, if we multiply the sum of the first two numbers (3+5=8) by the third number (8*3=24) and add it to the sum (24+8=32), we get 41.

For the third equation, 5+4+6=43, if we add the first two numbers (5+4=9) and multiply it by the third number (9*6=54), we get 43.

Similarly, in the fourth equation, 2+7+3=31, if add the first two numbers (2+7=9) and multiply it by the third number (9*3=27), we get 31.

Based on the patterns observed, for 6+7+3, we can add the first two numbers (6+7=13) and multiply it by the third number (13*3=39). Therefore, the value of 6+7+3 is 39.
