x=6
It's 4, because 7 fours total 28.
7x=42 x=42/7 or, x=6
if the equation was 7x = 42. The answer would be x = 6
n= 7
6m = 42 Divide both sides by 6: m = 7
7x = 42 so x = 42/7 and therefore x = 6
6
42
The answer to the equation 7 times 42 equals 294. This is taught in math.
That only works for people who are eleven.
7x-3=39 7x=42 x=6
x-29 = 13+2x x-2x = 13+29 -x = 42 x = -42
