Question

Can someone help me with 5,6,13, and 14 plz

Answer 1

|8+a|=18
So a will have two values since it’s going to change into the absolute value
The number inside the absolute value can be 18 or -18
8+a=18 a=10
8+a=-18 a=-26
a= -26 and 10

|5+m|=8
5+m=8 m=3
5+m=-8 m=-13
m= -13 and 3

answers attached below
13. x=10
14. x=8

Answer 2

5: 18-8=10 a=10. 6: 8-5=3 m=3.
