Three times a number increased by ten is equal to twenty less than six times the number. Find the number.

Let the number be x.

GIVEN

$3x + 10 = 6x - 20$

Solving, we get,

$3x - 6x = - 20 - 10\\- 3x = - 30\\x = 10$

∴The number = 3(10)+10

                        = 30 + 10

                        = 40
