3-2(9+2m)=m Find the m? please help me!
2 answers:
<h2>m= - 3</h2>
Step-by-step explanation:
3-2(9+2m)=m (we multiply 2 by each term inside the parenthesis)
3 - (18 + 4m) =m
3 - 18 - 4m =m
-15 - 4m - m =0 (we bring m before the equal)
-15 - 5m =0
-5m =15
m = 15 /-5
Answer:
m = -3
Step-by-step explanation:
3-2(9+2m)=m
3-18-4m=m
<em>Add 4m to both sides</em>
3-18=5m
-15=5m
<em>Divide both sides by 5</em>
-3=m
m= -3
