Let's simplify the given expression step by step:
-3(2x+7) = -6x - 21
(-5+5) = 0
-8(+1-2x) = -8 + 16x
(x-3) = x - 3
Now substitute these simplified expressions back into the equation:
-6x - 21 - 0 - (-8 + 16x) - (x - 3) = 0
Simplify further:
-6x - 21 + 8 - 16x - x + 3 = 0
Combine like terms:
-23x - 10 = 0
Add 10 to both sides:
-23x = 10
Divide by -23:
x = -10/23
Therefore, the solution to the equation -3(2x+7) (-5+5)-8(+1-2x)-(x-3)=0 is x = -10/23.
