The equation is 88 = 125 ![\"\"](\"http://c4anything.com/MathKey/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=c7a8c800d2df7d176b09fff75181eb8f.png\")
(u).
88 = 125 + u (Product of two same signs is positive)
\According to subtraction property of equality: If a = b, then a c = b c.
88 125 = 125 + u 125 (Subtract 125 from each sides)
88 125 = u (Additive inverse property: 125 125 = 0)
u = 37 (Subtract: 88 125 = 37)

Check:
\To check the solution, substitute u = 37 in original equation.
88 = 125 + u![\"\"](\"http://c4anything.com/MathKey/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=cf88eb4b75e2e087ff1d68b5148e102c.png\")
88 = 125 37
88 = 88 (Subtract: 125 37 = 88 )
Compare the values, the equation is true. The solution is u = 37.
