1. 9x-7- -7
2. 2(n+5)=-2
3. -9x+1= -80

Answer 1

please explain the question further because I can't seem to understand what you wrote

Answer 2

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)
