Question

2 times the sum of the number × and 7is13 find the number​

Answer 1

Answer:

2( x + 7 ) = 13

= 2x + 14 = 13

= 2x = 13 - 14

= 2x = -1

= 2x = -1/2

= x = -1/2

Answer 2

So, we have to find the no. x here.

According to question,

we get 13 if we add 2 times the sum of 7 and x.

here's the equation:

• 2(x+7) = 13

• 2(x + 7 ) ×1/2 = 13 ×1/2 (multiplying 1/2 with both sides)

• (x+7) = 13/2

• x+7 -7= 13/2 - 7 (subtracting 7 from both sides)

• x= 13-14

2

• x= -1

2

So, by these steps we get the value of 'x' that is -1/2.

-1/2 is the required number.
