hope helpful ~
I solved it and i think the answer is 20 :)
A negative number * another negative number gives a positive value
A positive number * another positive number also gives a positive value
The solutions are -4, 4
Hope this helps :)

Answer:
Step-by-step explanation:
Two angles are supplementary when their sum is 180
∠AXB + ∠BXC = 180° {Supplementary angles}
8x + 10 + 2x - 20 = 180
Add the like terms
10x - 10 = 180
10x = 180 + 10
10x = 190
x = 190/10
x = 19°
∠AXB = 8x + 10
= 8 * 19 +10
= 152 + 10
∠AXB = 162
