✔ 最佳答案
first solve equation:

8x- 10 = 6
Add 10 from both sides
8x= 16
Divide 8 from both sides
x= 2

Since l,l means absolute value, positive integer is remained same.

So you have to set 8x - 10 to both 6 and -6, since it is asking for the absolute value.

8x - 10 = 6...... x = 2
8x - 10 = -6...... x = 1/2

8 x - 10 = 6
8 x = 16
x = 2

8 x - 10 = - 6
8x = 4
x = 1/2

x = 1/2 , x = 2

8x- 10 = 6
8x= 16
x= 2

and

8x- 10 =- 6
8x= 4
x= 1/2

|8x - 10| = 6
8x - 10 = ± 6
8x = 10 ± 6
x = (10 ± 6) / 8 = 2, 1/2

Answer: x = 2 and x = 1/2

X=2 8 times 2 is 16. 16-10=6
