Answer 2

Answer:

m = -1.5

Step-by-step explanation:

7(m+2) + 19/2 = 13

7m + 14 + 19/2 = 13                     [ LCM of 1, 1, 2 = 2 ]

14m/2 + 28/2 + 19/2 = 13

(14m + 28 + 19)/2 = 13

(14m + 47)/2 = 13

14m/2 + 47/2 = 13

7m + 23.5 = 13

7m = 13 - 23.5

7m = -10.5

m = -10.5/7

m = -15/10

m = -1.5
