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"#
