Answer:
x = 20
Step-by-step explanation:
This isn't too difficult once you understand it.
The bottom left angle of the left triangle (on the other side of 110), that angle is congruent to the 70 degrees angle. that angle is 70 degrees. y = 90 degrees, 90 + 70 = 160
180 - 160 = 20

In the picture I send above shows the step by step how to get the answers. Cheers!
If they have the same charge
x+x+x+x+x+x+x=-42
7x=-42
x=-6
so to check our answer
-6-6-6-6-6-6-6=-42
-12-12-12-6=-42
-24-18=-42
-42=-42
-8+4x=-20x-25+7x
4x+20x-7x=-25+8
17x=-17 /17
x=-1
-x-29=13+2x
-29=13+3x
-42=3x
x=-14
