Simplify by combining like terms -(m+n)+2 (m-3n)

-(m+n)+2(m-3n)

-m+n+2m-6n

-m+2m+n-6n

m-5n

m -7n

Step-by-step explanation:

-(m+n)+2 (m-3n), distribute in the first parenthesis the -1 and in the second parentheses the 2

-m -n + 2m -6n , group like terms

-m + 2m -n -6n , combine like terms

     m     -7n

its not b

step-by-step explanation:

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
