The sum of twice a number and six is 14 find the number.

Let the number be x. So,

2x + 6 = 14

=> 2x = 14 - 6

=> 2x = 8

=> x = 8/2

=> x = 4

So, the number is 4.

Solution

here,given,

2x+6=14(let the unknown number be x)

or,2x=14-6

or,2x=8

or,x=8÷2

or,x=4

We know that,

x=4

So,2x=2×4

=8
