The answer of the question is correct but i don’t understand all the equations
Instead of working with 49 directly.
Try to set a small number, like, 7
1+7=8
2+6=8
3+5=8
1+2+3+4+5+6+7
=4+3×8
4←(7+1)÷2
3←(7-1)÷2
From here
U will have the idea the equation for number 49
Please feel free to ask if you still don't understand
