Answer: 8.5 and 3.5
Step-by-step explanation:
Let the two numbers be a and b
Represent the question in an equation:
a + b = 12....... eqn 1
a - b = 5...........eqn 2
2a = 17 addition of both equations
Divide both sides by 2
a = 17/2
a = 8.5
To find b, Substitute the value of a into equation 2
a - b = 5, where a = 8.5
8.5 - b = 5
Make b the subject
-b = 5 - 8.5
-b = -3.5, divide both sides by -1
b = 3.5
Check with reference to the question:
8.5 + 3.5 = 12
8.5 - 3.5 = 5
I hope this is clear, please mark as brainliest answer.
