Question

How are the solutions to the following two equations related m+5=72
m+72=5

Answer 1

To see how they are related, let us solve the two equations.

FIRST EQUATION


`m + 5 = 72`


`\rightarrow \: m = 72 - 5`


`\rightarrow \: m = 67`

SECOND EQUATION


`m + 72 = 5`


`\rightarrow \: m = 5 - 72`


`\rightarrow \: m = - 67`

Hence the solutions to the two equations are ADDITIVE INVERSE of each other.
