Answer:

#m=-7#

Explanation:

Simplify the right side by collecting like terms.

#23=-3m+2#

That is : #-3m+2=23 " reversing the equation"#

subtract 2 from both sides.

#-3mcancel(+2)cancel(-2)=23-2#

#rArr-3m=21#

To solve for m, divide both sides by - 3.

#(cancel(-3) m)/cancel(-3)=21/(-3)#

#rArrm=-7" is the solution"#
