Answer:

Step-by-step explanation:
Six times a number is decreased by fourteen, the result is 124.
Write an equation that represents this
(6 * x) - 14 = 124

x = 23
The unknown number is 
Hope this helps :)
the two consecutive numbers are 56 and 57
x+x+1=113
2x+1=113
2x=113-1
2x=112
x=112/2
x=56
therefore, x=56
x+1= 56+1= 57
