Answer:

x=10

Step-by-step 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
