70=(-7(2x+6)=2

70=(-7(2x+6)

-10=2x+6

x=-16/2

x=-8

(-7(2x+6)=2

2x+6=-2/7

2x=-2/7-6

x=-1/7-3=-22/7=-3.14

10(11n+5)=-10n-10+90n

10(11n+5)=80n-10

11n+5=8n-1

3n=-6

Problem has answered the 2nd one correctly.  thank you Problem.

the first one cannnot be answered correctly because it doesn't make sense.

There is an odd number of brackets. - which simply is not allowed

And there are 2 equal signs which also does not make sense.

Sorry Kaylaa , you will need to edit your question to make it make sense!
