Question

The sum of 2 times a number and 10 is the same as 6 times the difference of the number and 1. What is the number?

Answer 1

Answer:

4

Step-by-step explanation:

if the required number is 'x', then the sum of 2 times the number and 10 is 2x+10; the difference of the number and 1 is x-1. Using these two equation it is possible to make up the common one:

2x+10=6(x-1);

4x=16;

x=4.

Answer 2

The unknown number is 4

How can we find unknown number?

We will assume the unknown number a variable. Then solve the linear equation to find unknown number.

We can find unknown number as shown below:

Let the unknown n number be x.

2x+10=6(x-1)

2x+10=6x-6

2x-6x=-6-10

-4x=-16

4x=16

x=4

Hence, the unknown number is 4.
