Question

solve the equation P+12=32 and state which axiom do you use here.

Answer 1

Hello!

$\star\: \bf\small{ANSWER}$ :

$\boxed{\red{\bf{p = 20}}}$

$\star \: \bf\small{EXPLANATION}$ :

$\sf p + 12 = 32 \\ \\ \implies \sf p + \cancel{12} - \cancel{12} = 32 - 12 \\ \\ \implies \boxed{\red{\bf{p = 20}}}$

$\star\: \bf\small{AXIOM}$ :

When equals are subtracted from equals their remainders are also equal.

Cheers!

Answer 2

We have P +12 = 32 => P+12-12=32-12 =>P=20. Àxiom used : when equals are from equals then remainder are equal.
