Jaelyn Gordon · Answer 1

12 + 10h = 8h + 4

12 + 10h = 4 + 8h

12 + 10h = 4 + 8h

12 + 10h + - 8h = 4 + 8h 10h + - 8h = 2h 12 + 2h = 4 + 8h + - 8h

8h + - 8h = 0 12 + 2h = 4 + 0 12 + 2h = 4

12 + - 12 + 2h = 4 + - 12

12 + - 12 = 0 0 + 2h = 4 + - 12 2h = 4 + - 12

4 + - 12 = - 8 2h = - 8

h = - 4

h = - 4

Annabel Villa · Answer 2

10h + 12=8h+4

Subtract 4 from both sides

10h+8=8h

SUbtract 10h from both sides

8=-2h

Divide both sides by negative 2

h=-4
