To solve the equation (10x - 9 = 21), first add 9 to both sides to get (10x = 30). Then, divide both sides by 10 to find (x = 3). Thus, the solution to the equation is (x = 3).
90
It is false because 10x9 does not equal14x7. If they were equal then it would be equal.
21 equals dots on a dice
28*21 equals 84

5q-29 equals 21 5q equals 50 q = 5

21 feet equals 6.4008 metres.
3 and 7 multiplies to 21 and equals to 10
How about: 1*21 = 21 or 3*7 = 21
x = ab x = 21*37 x = 777
n=21
