-2(m+4)-9=5−2(m+4)−9=5


m=?


Sagot :

Answer:

there are no solutions to m

Step-by-step explanation:

[tex] - 2(m + 4) - 9 = \\ 5 - 2(m + 4) - 9 = 5[/tex]

[tex] - 2m - 8 - 9 = 5 - 2m - 8 - 9 = 5[/tex]

[tex] - 2m - 17 = - 2m + 5 - 8 - 9 = 5[/tex]

[tex] - 2m - 17 = - 2m - 3 - 9 = 5 [/tex]

[tex] - 2m - 17 = - 2m - 12 = 5[/tex]

[tex] - 2m = - 2m + 5 = 5[/tex]

[tex] - 2m = - 2m + 5 = 5 \\ - 2m = - 2m = 0 \\ - 2m = m = 0 \\ - 2(0) = 0 \\ 0 = 0[/tex]

check

[tex] - 2(0 + 4) - 9 = 5 \\ - 2(0 + 4) - 9 = 5 \\ \\ 0 - 8 - 9 = 5 \\ 0 - 8 - 9 = 5 \\ - 17 = 5 \\ there \: are \: no \: solutions[/tex]
