Question

Solve the equation a + 5 = 20 and state which axiom do you use here.​

Answer 1

Answer:

15

Step-by-step explanation:

a+5=20

a=20-5

a=15

Answer 2

Answer:

Required value of a is 5 and here I used subtraction axiom.

Step-by-step explanation:

Here we want to find axiom.

It is very easy.

Axiom is a famous word of mathematics.

There are four types of axioms are present i.e addition, subtraction,multiplication and division.

$3 + 5 = 8$is the example of addition axiom.

$8 - 8 = 0$is the example of subtraction axiom.

$10 \times 5 = 50$is the example of multiplication axiom.

And $15 \div 3 = 5$is the example of division multiplication.

Here given,

$a + 5 = 20$

$a = 20 - 5 = 15$

It is clear that it is a example of subtraction axiom.
