Given the numerical statement:

A number is 8 more than another number =23

Solution:

The numerical statement can be written as,

( x + 8)  + x = 23

Combine like terms.

 x + 8 + x = 23

2x + 8 = 23

Transpose 8 to the other side of the equation, hence, we must take note that in tranposing a number, the sign changes.

2x = 23 - 8

2x = 15

Divide both sides by 2 in order to determine the value of x.

2x /2 = 15/2

x = 7.5

(7.5 + 8) = 15.5

Final answer:

x = 7.5

x + 8 = 15.5
