Question

solve the equation x-3=12 and state the axiom you use here

Answer 1

hey mate.....

here we can use the 3rd axiom that
if equals are added to equals then the whole is also equal

so we add 3 to both sides
x-3 = 12
x-3+3 = 12+3
x = 12+3
x = 15

HOPE THIS HELP YOU ☺☺

Hey Mate!
________________________________


$x- 3 = 12 \\ x = 12 + 3 \\ x = 15$

Verification:

$15 - 3 \\ = 12$

Hence, verified!
