2. Thirty decreased by 6 times a number is the same as 16 more than the number. Find the number.

x=2

Step-by-step explanation:

Let x be the number

30 - 6x = x+16

Add 6x to each side

30 -6x+6x = x+16+6x

30 = 7x+16

Subtract 16 from each side

30-16 = 7x+16-16

14 = 7x

Divide each side by 7

14/7 = 7x/7

2 =x

2

Step-by-step explanation:

let the number be x

given, 30 decreased by 6 times the number=30-6x

that is same as 16 more than the number= x+16

equating these 2 equations since they are equal

30-6x=x+16

6x+x=30-16

7x=14

x=2

The req. number is 2
