Solution for log(x+y)=logx+logy equation:


Simplifying
log(x + y) = logx + logy
(x * glo + y * glo) = logx + logy
(glox + gloy) = logx + logy

Add '-1glox' to each side of the equation.
glox + -1glox + gloy = glox + -1glox + gloy

Combine like terms: glox + -1glox = 0
0 + gloy = glox + -1glox + gloy
gloy = glox + -1glox + gloy

Combine like terms: glox + -1glox = 0
gloy = 0 + gloy
gloy = gloy

Add '-1gloy' to each side of the equation.
gloy + -1gloy = gloy + -1gloy

Combine like terms: gloy + -1gloy = 0
0 = gloy + -1gloy

Combine like terms: gloy + -1gloy = 0
0 = 0
