Given the numerical statement:
The sum of two numbers is 45. the smaller number is 15 less than the larger number.
Determine the number.
Solution:
The given can be represented as,
Let x = larger number
x - 15 = smaller number
Equate the representation in an equation, whereas the sum is 45, therefore we separate the two representation with a plus sign.
( x ) + ( x - 15) = 45
Solve for x.
x + x - 15 = 45
2x - 15 = 45
2x = 45 + 15
2x = 60
Divide both sides by 2 in order to determine the value of x.
2x/2 = 60/2
x = 30
Final answer:
x =30
