Answer:
m=-1
Step-by-step explanation:
2.3-5m=9.8+2.5m
+5m=9.8+5m
2.3=9.8+7.5m
-9.8 -9.8
-7.5=7.5m
/7.5 /7.5
-1=m
Answer:
[tex]m=-1[/tex]
Step-by-step explanation:
[tex]2.3-5m=9.8+2.5m[/tex]
⟹ Multiply both sides by 10:-
[tex]2.3\times \:10-5m\times \:10=9.8\times \:10+2.5m\times \:10[/tex]
[tex]23-50m=98+25m[/tex]
⟹ Subtract 23 from both sides:-
[tex]23-50m-23=98+25m-23[/tex]
[tex]-50m=25m+75[/tex]
⟹ Subtract 25m from both sides:-
[tex]-50m-25m=25m+75-25m[/tex]
[tex]-75m=75[/tex]
⟹ Divide both sides by -72:-
[tex]\frac{-75m}{-75}=\frac{75}{-75}[/tex]
[tex]m=-1[/tex]
