-(m-8)= -8m+29

-1(m-8)=-8m+29-------------Note: there is always an invisible 1 in front

-m+8=-8m+29---------------Subtract both sides by -8

-m=-8m+21-------------------Add both sides by +m

0=-7m+21---------------------Add +7m to both sides

7m=21 -------------------------Divide both sides by 7

m=3
