Answer 2

Answer:

11.7

Step-by-step explanation:

Let the number be x

[thrice the number means 3 times the number. So we can write 3 times x or 3x , increased by 10 means add 10 ]

3x + 10 = 45

3x = 45 - 10      ( + turns - when you bring to other side )

3x = 35

x= 35/3 = 11.7   (multiplication turns to division when you bring to other side)

Hope this helps :)
