Answer 1

(4 3/8 х + 5 1/16) * 4/15 = 5/12х + 2 2/5
1 1/6 х + 1 7/20 = 5/12х + 2 2/5
1 1/6 х -5/12 х = 2 2/5 - 1 7/20
14/12 х - 5/12 х = 2 8/20 - 1 7/20
3/4 х = 1 1/20
х = 1 1/20 : 3/4 
х = 21/20 * 4/3
х=7/5
х=1 2/5

Answer 2

7/6х+81/60=5/12х+12/5
7/6х-5/12х=12/5-81/60
3/4х=63/60
х=63/60:3/4
х=63/60*4/3
х=21/15=1,4
