Answer:
x = that number
x = 10a + 3a =13a
x_reverse = 3ax10+a =31a
Have:
13a+36 =31a
=> a =2
=> x =26
The number is 26.
Step-by-step explanation:
Let the number be xy.
Then:
y = 3x also:
10x + y + 36 = 10y + x
9x - 9y = = -36
x - y = -4
Substituting y = 3x in the above equation:
x - 3x = -4
-2x = -4
x = 2.
and y = 3*2 = 6.
75
700-400=300
6-2=4
300/4=75
