I think you forgot to put something in your question
I can’t help if I don’t know the question
It is 255/866 convert to decimal
10. 5 x (3+7) = 50
11. ?
12. 100 - (3x6+5) - 4 gets your 73, you cannot get 63 (from my understanding, but make sure)
Answer:
Hey there!
-36+7x=76-x
-36+8x=76
112=8x
x=14
Let me know if this helps :)
