2x-10=-11<< add 10 to both sides
2x=-1 <<< divide by 2
x=-1/2

2(x – 5) = –11
(x – 5) = –11/2
x=-11/2+5
x= - 1/2

2(x-5)= -11 = 2x-10= -11, add 10 to both sides, leavin 2x= -1, you then divide both sides by 2 to get X by itself, leaving you with 2x/2=-1/2, and that gets x on its own, and the answer of
x= -1/2 or x= -.5

2(x-5)=-11
You must deal with Brackets first so multiply 2 with x & 5
2x-10=-11
Like terms on same side, x alone because it's unknown
then remember to change Signs +/- Reason is when #s crossover "=" it goes from - to + or the other way around
2x=-11+10
From here work to get:
2x=-1
Almost there so we divide each side with 2 to derive the true value of x
x=-1/2 or -0.5

expand first :
2x -10 = -11
add 10 to both sides
2x -10 + 10 = -11 + 10
simplify
2x = -1
divide both sides by 2
2x/2 = -1/2
x = -1/2

2(x – 5) = –11
2x - 10 = -11
2x = -11 + 10
2x = -1
x = -1/2

by opening the brackets
2x - 10 = -11
taking x on one side
-11 + 10= 2x
1=2x
taking x on one side
x=1/2

2x - 10 = -11
2x = -11 + 10
2x = -1
x = -1/2
