Answer:
x=13
Step-by-step explanation:
we have from the statement:
23 = (x-6)+9+(2x-19)
23 = x+3+2x-19
23 = 3x -16
23+16 = 3x
39 = 3x
x=39/3
NK = 23 and NK = (x - 6) + 9 + (2x - 19) = (x + 2x) + (-6 + 9 - 19) = 3x - 16
The equation
3x - 16 = 23 add 16 to both sides
3x = 39 divide both sides by 3
x = 13
