Answer:

The number is 35

Step-by-step explanation:

Let x be the number

1/5 x + 3x

=

2x + 42                 Break the question into phrases and solve 1 phrase at a time.

1/5 = 0.2

0.2x + 3x = 2x + 42              Combine the left

3.2x = 2x + 42                       Subtract 2x from both sides

3.2x - 2x = 42                        Combine

1.2x = 42                                Divide by 1.2

x = 42/1.2

x = 35
