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
