70=(-7(2x+6)=2 ..................... and 10(11n+5)=-10n-10+90n
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!
