Solution:
Note that:
[tex]x+23=2\mleft(2x+25\mright)[/tex]
Applying the distributive property, this is equivalent to:
[tex]x+23=4x+50[/tex]
now, putting the like terms together we obtain:
[tex]4x-x=\text{ 23-50}[/tex]
this is equivalent to:
[tex]3x\text{ = -27}[/tex]
solving for x, we get:
[tex]x\text{ = -}\frac{27}{3}=-9[/tex]
so that, we can conclude that the correct answer is:
[tex]-9[/tex]
