Answer:

48,30

Step-by-step explanation:

take the two numbers as x and y

x+y=78

x-y=18

add the two equations

2x=96

x=48

substitute x value to equation

y=30

The two numbers will be equal to 48 and 30 respectively.

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

It is given that the sum of the two numbers is 78, and their difference is 18.

Let the two numbers be x and y. Form the two equations from the given data in the question.

x+y=78

x-y=18

Add the two equations to get the value of x.

2x=96

x=48

Substitute x value to the equation.

x - y  = 18

48 - y = 18

y = 48 - 18

y = 30

Therefore, the two numbers will be equal to 48 and 30 respectively.
