Answer:
m= 5
Step-by-step explanation:
-7m-5(m+5)= -85
-7m-5m-25= -85
-12m-25= -85
-12m= -60
/-12 /-12
m=5
−7m−5(m+5)=−85
−7m+(−5)(m)+(−5)(5)=−85
−7m+−5m+−25=−85
combine the like terms: (−7m+−5m)+(−25)=−85
−12m+−25=−85
add 25 to both sides : −12m−25+25=−85+25
divide both sides by -12
−12m /−12 =
−60 /−12
