Answer:
Exact form : m=13/5
Decimal form : m=2.6
Mixed Number form : m=2 3/5
Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.
Hope this helps you out! ☺
To find the value of "m", you need to isolate/get the variable "m" by itself in the equation:
1 - 10 = 4 - 5m You can first combine 1 and -10
-9 = 4 - 5m Subtract 4 on both sides
-9 - 4 = 4 - 4 - 5m
-13 = -5m Divide -5 on both sides to get "m" by itself
[tex]\frac{-13}{-5} =\frac{-5m}{-5}[/tex] (two negative signs cancel each other out and become positive)
[tex]\frac{13}{5} =m[/tex]
PROOF
1 - 10 = 4 - 5m Substitute/plug in [tex]\frac{13}{5}[/tex] into "m"
[tex]1 -10=4-5(\frac{13}{5} )[/tex]
1 - 10 = 4 - 13
-9 = -9
