let numbers be: x and y
x+y=3.9 x-y=0.9
Adding both
2x = 4.8 x = 2.4
2.4+y=3.9 y=3.9 - 2.4 y = 1.5
The **two numbers **are 2.4 and 1.5 respectively.
What is a numerical expression?
A **numerical expression **is an algebraic information stated in the form of numbers and **variables **that are unknown. **Information **can is used to generate numerical expressions.
Consider the **numbers **be: x and y
Given that **sum **of two **decimal numbers **is 3.9. Their **difference **is 0.9 and their **product **is 3.6
Then the** system of equation**;
x+y=3.9
x-y=0.9
**Adding **both the equation we get;
2x = 4.8
x = 2.4
Now for the **value **of y.
2.4+y=3.9
y=3.9 - 2.4
y = 1.5
Therefore, the **two numbers **are 2.4 and 1.5 respectively.
