2)2k+7=12-3k
3)10-4k=18-6x
4)5m-3,2=2m+2,8
5) 5n+12=25-4n+5

Answer 1

5j-9=3j+5

5j - 3j = 5 + 9

2j = 14

j = 14/2

j = 7

2k+7 = 12-3k

2k + 3k = 12 - 7

5k = 5

k = 5/5

k = 1

10-4k=18-6x

6x - 4x = 18 - 10

2x = 8

x = 8/2

x = 4

5m-3,2=2m+2,8

5m - 2m = 2,8 + 3,2

3m = 6

m = 6/3

m = 2

5n+12 = 25-4n+5

5n + 4n = 30 - 12

9n = 18

n = 18/9

n = 2
