12x - 23 + 2x = -5
 14x-23=-5 /+23
 14x=18
 x=18/14=9/7
x=\(1 \frac{2}{7}\)

\(12x-23+2x=-5\)

combine the like terms (x) so,

\(12x+2x-23=-5\)

so, this will give you: \(14x-23=-5\)

now, remove the numbers

so, \(14x=-5+23\)

this will give you : \(14x+18\)

\(x = \frac{18}{14}\)

\(x = 1.285714286\)
