No its not
Step-by-step explanation:
When 42(x + 14y) is simplified:
42(x + 14y)

42*x
42x
42*14y
588y
42x+588y
Therefore 42x-56 is NOT EQUIVALENT to 42(x + 14y) but is equivalent to 42+588y
Mr. Reed DATA:
rate = 40 mph ; time = x 4.5 hrs ; distance = 40x miles
-----
Mrs. Reed DATA:
rate = 60 mph ; time = x hrs ; distance = 60x - 210 miles
------
Equation:
40x = 60x -210
-20x = -210
x = 10.5 hrs
x-3.5 = 7 hrs (Mr. Reed's time)
