Answer:
m= -20
Explanation:
0.45m-9=0.9m
-9+0.45m=0.9m
Solve:
-9+0.45m=0.9m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-0.9m' to each side of the equation.
-9 + 0.45m + -0.9m = 0.9m + -0.9m
Combine like terms: 0.45m + -0.9m = -0.45m
-9 + -0.45m = 0.9m + -0.9m
Combine like terms: 0.9m + -0.9m = 0.0
-9 + -0.45m = 0.0
Add '9' to each side of the equation.
-9 + 9 + -0.45m = 0.0 + 9
Combine like terms: -9 + 9 = 0
0 + -0.45m = 0.0 + 9
-0.45m = 0.0 + 9
Combine like terms: 0.0 + 9 = 9
-0.45m = 9
Divide each side by '-0.45'.
m = -20
Simplifying
m = -20
Hope this helps :)
