m/5 + 8 = -7 m/5 = -15 m = -15 x 5 m = -75
5/8 plus m = 1 easy4/4=167/67=18/8=1m=3/8
(15/m) - m + 8 = 1015/m - m = 215 - m2 - 2m = 0 or m2 +2m - 15 = 0This factoises as (m +5)( m - 3), so m = 3 or -5

8 km is longer then 8 m as 5 m then 5 mm

m/5 + 8 = -7 m/5 = -15 m = -15 x 5 m = -75
If 3m - 7 = 8, then m = 5

5/8 plus m = 1 easy4/4=167/67=18/8=1m=3/8
1500 m + 850 m + 2800 m = 5150 m or 5.15 km
(15/m) - m + 8 = 1015/m - m = 215 - m2 - 2m = 0 or m2 +2m - 15 = 0This factoises as (m +5)( m - 3), so m = 3 or -5
510 cm or 5.10 m
-8 + (5m - 6m) = -8 + (-m) = -8 - m
This cannot be true unless m is equal to 0.
