It is simply 2m - 5/9, nothing more, nothing less. It cannot be simplified or factorised. It cannot be evaluated without knowing the value of m.

-1/2m = -9 To solve this: Multiply by 2m: -1 = -9*2m Divide by -9: -1/-9 = 2m Divide by 2: (-1/-9)/2 = m Work it out: -1/-9 = 0.111... (the 1 is recurring) 0.111... / 2 = 0.0555... (the five is recurring) So x = 0.055... or 5/90
2m - 9 = 12→ 2m - 9 + 9 = 12 + 9→ 2m = 21→ 2m ÷ 2 = 21 ÷ 2→ m = 101/2 = 10.52m - 9 = 12Add 9 to each side of the equation:2m = 21Divide each side by 2 :m = 10.5
2m-5=17 +5=+5 ___ 22 Therefore, 2m = 22 22 / 2 = 11 m = 11
2m + 5 = 10 Therefore, 2m = 5 m = 5/2 m = 2.5
m=1/2 -2m=16m-9 -18m=-9 m=1/2
