Answer 1

so because the denominator is 2x+6 so than this not can be equal zero
- you need to get for what value of x this 2x+6 will be equal zero

Answer 2

do you know why the denominator not can being equal zero ?

Answer 3

so because than the fraction will be undefined

Answer 4

can

Answer 5

can you make the calcule

Answer 6

so make 2x+6=0 than assum to both sides -6 and will get

2x=-6 now divide both sides by 2
2x/2 =-6/2
x=-3

ok ?

Answer 7
