Answer:


x=10

Explanation:

Three times a number increased by ten equal to twenty less than six times a number. Let the number be
x.


3x + 10 = 6x-20

Add
-6x and
-10 on both sides.


3x-6x = -20-10


-3x=-30

Cancel the negative signs on both sides.


3x=30

Divide
3 on both sides.


x=30/3


x=10
