Question

What is the solution set for |2x – 6| – 7 = 7?

Answer 1

|2x - 6| = 14

that gives you 2 equations

2x-6 = 14

and

2x-6 = -14

solve for x for both of them

2x-6 = 14 ---> 2x = 20 --->x=10

2x-6 = -14 ---> 2x = -8 ---> x=-4


so your solution set is x = {-4,10}

Answer 2

ok thank you soo much

Answer 3

for positive charge we can write
2x-6-7=7
=>2x-13=7
=>2x=7+13
=>2x=20
=>x=10
for negative charge we can write
-(2x-6)-7=7
=>-2x+6-7=7
=>-2x-1=7
=>-2x=7+1
=>-2x=8
=>x=-4
