12x - 23 + 2x = -5
 14x-23=-5 /+23
 14x=18

[tex]12x-23+2x=-5[/tex]

combine the like terms (x) so,

[tex]12x+2x-23=-5[/tex]

so, this will give you: [tex]14x-23=-5[/tex]

now, remove the numbers

so, [tex]14x=-5+23[/tex]

this will give you : [tex]14x+18[/tex]

[tex]x = \frac{18}{14} [/tex]

[tex]x = 1.285714286[/tex]
