2.2(n+5)=-2
2n+10=-2
2n=-2-10
2n=-12
n=-6
(first we open the bracket by using two multiply n and + 5 which give us 2n + 10 equal to -2 next we collect like terms by taking 10 to the other side which make it-10 they will divide by two which give us -6)
3.-9x+1=-80
-9x=-80-1
-9x=-81
x=9
(-9x + 1 =-81 first we take one to the other side which makes it -1 then weadd-80 - 1 which give us - 81 they will divide by -9 minus will cancel minus which gives us x=nine)
