The answer is 42. 6 x 7 equals 42. 21 x 2 equals 42.
4 x 10000
X * 3 = 42 X = 42/3 X = 14
42 x 42 = 1764 42 + 42 = 84
x/3 = 42 Therefore, 42 x 3 = x x = 126
if the equation was 7x = 42. The answer would be x = 6
5+x=42. 42-5=37 x=37
x = 42 / 6Therefore x = 7
-55
7x=42 x=42/7 or, x=6
x=42
7x = 42 so x = 42/7 and therefore x = 6
