The equation is 0.97 + a = 2.6
\Apply subtraction property of equality: Subtract 0.97 from each side.
\a + 0.97![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=c7a8c800d2df7d176b09fff75181eb8f.png\")
0.97 = 2.60.97
a + 0 = 2.60.97 (Apply additive inverse property: 0.970.97 = 0)
a = 2.60.97 (Apply additive identity property: z + 0 = z)
