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
