Q5. Solve the equation a -15 = 25 and state which axiom do you use here.​

Answer 1

a - 15 = 25

___________ [ GIVEN ]

• We have to find the value of a.

____________________________

→ a - 15 = 25

Add + 15 on both sides

→ a - 15 + 15 = 25 + 15

→ a + 0 = 40

→ a = 40

» Euclid's second axiom is used here.

_____________________________

$\huge{\bold{a\:=\:40}}$

__________ [ ANSWER ]

_____________________________

✡ VERIFICATION :

From above calculations we have a = 40

Put value of a in this equation : a - 15 = 25

=> (40) - 15 = 25

=> 25 = 25
