Answer:
Tens digit, x = 3
Unit digit, y = 8
Number = 38
Step-by-step explanation:
Let the 2 digit number = xy
y = x + 5 - - - (1)
10x + y = 4(x + y) - 6
10x + x + 5 = 4(x + x + 5) - 6
11x + 5 = 4(2x + 5) - 6
11x + 5 = 8x + 20 - 6
11x + 5 = 8x + 14
11x - 8x = 14 - 5
3x = 9
x = 9/3
x = 3
From (1)
y = x + 5
y = 3 + 5
y = 8

There isn't a way to show work other than drawing a number line
Amount of money that Caitlin in her account = $ 402
In each week , she withdrew $ 15.
Let number of weeks she had paid money for Swimming lesson = $ 237
Writing the above statement in equation form
⇒ 402 - 15 n = 237
⇒ 402 - 237 = 15 n
⇒ 15 n = 165
Dividing both side by 15, we get
n= 11
→Number of weeks that Caitlin had learnt Swimming = 11 Weeks
