-(x-11)=10 =>-x+11=10 => -x=10-11 => -x=-1 =>x=1 ans --7x+4x=-24 =>-3x=- 24 x=24/3=8 ans. - -5x-3x = -56 => -8x=- 56 =>x=56/8=7 ans.

To explain it in words and have you work through it yourself would be best, but try to follow my steps and understand what was done to get from one line to the next.
-(x - 11) = 10
-x +11 =10
-x = 10 - 11
-x = -1
x = 1
-7x + 4x = -24
-3x = -24
x = -24 ÷ -3
x = 8
-5x - 3x = -56
-8x = -56
x = -56 ÷ -8
x = 7

-(x - 11) = 10
-x + 11= 10
-x = 10 - 11
-x = - 1
(-x=-1) -1
x=1
-7x + 4x = -24
-3x= -24
x = -24 / -3
x= 8
-5x - 3x + -56 (did u mean equals - 56?)
-8x = -56
x = -56 / -8
x=7

-(x-11)=10 you have to distribute the negative then solve for x. it breaks down to
-(x-11)=10
-x+11=10
11=10+x
1=x
for the next one
-7x+4x=-24
-3x=-24
x=-24/-3
x=8
the last one
-5x-3x+ -56
you are not clear on what it equals so I am making the assumtion that-56 is supose to be =56
-5x-3x=56
-8x=56
x=-7
Hope this helps

-(x-11)=10
-x+11=10 (distribute the negative sign)
11-10=x
1=x
-7x+4x=-24
-3x=-24
x=8
-5x-3x=-56
-8x=-56
x=7

I remember Algebra last year.
1.
-(x - 11) = 10
-x + 11 = 10
-x = -1
x = 1
2.
-7x +4x = -24
-3x = -24
x = 8
3.
-5x - 3x + -56
-8x + (-56)???????????
That is not an equation.
If that says:
-5x - 3x = -56, then
-8x = -56
x = 7
If it says -5x -3x = 56, then
-8x = 56
x = -7
Hope this helped.

-X+11=10
11=10+X
11-10=X
X=1
-7X+4X=-24
4X=7X-24
4X+24=7X
24=7X-4X
24=3X
24/3=X
X=8
-5X-3X=-56
-3X=-56+5X
56-3X=5X
56=5X+3X
56=8X
56/8=X
