The equation is 19 + p = 6.
\According to subtraction property of equality: if a = b, then a ![\"\"](\"/MathKey/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=c7a8c800d2df7d176b09fff75181eb8f.png\")

c.
19 + p 19 = 6 19 (Subtract 19 from each sides)
p = 6 19 (Additive inverse property: 19 19 = 0)
p = 13 (Subtract: 6 19 = 13)

Check:
\To check the solution, substitute p = 13 in original equation.
19 + p = 6![\"\"](\"/MathKey/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=cf88eb4b75e2e087ff1d68b5148e102c.png\")
19 13 = 6
6 = 6 (Subtract: 19 13 = 6)
Compare the values, the equation is true. The solution is p = 13.
