I will use the box method, and I hope it helps you!
After looking at the picture, this is not the answer quite yet.
Subtract 4x from 9x.
9x-4x=5x
So, the answer will be +5x-36
Answer:
Simplified
2/5y + 1/5x - 413/50
or
0.4y + 0.2 x - 8.26
Step-by-step explanation:
Answer:
Let ten's place digit =x and unit place digit =y
Number=10x+y
x+y=5 ...(i)
10x+y−9=10y+x
9x−9y=9x−y=1 ...(ii)
from (i) and (ii) we get,
x=3,y=2
∴Number=10×3+2=32.
