Question

-19p + __ = 0
19p + __ = 0
32p + __ = 0
-32p + __ = 0
-19p
32p
-32p
19p

Explanation:

Step1: Solve for first blank

Let $x$ be the blank. $-19p + x = 0 \implies x = 19p$

Step2: Solve for second blank

Let $x$ be the blank. $19p + x = 0 \implies x = -19p$

Step3: Solve for third blank

Let $x$ be the blank. $32p + x = 0 \implies x = -32p$

Step4: Solve for fourth blank

Let $x$ be the blank. $-32p + x = 0 \implies x = 32p$

Answer:

$-19p + \boldsymbol{19p} = 0$
$19p + \boldsymbol{-19p} = 0$
$32p + \boldsymbol{-32p} = 0$
$-32p + \boldsymbol{32p} = 0$
