Question

Pls answer these questions:
1) 1/3 of a number is 13. The number is?

2) if 6 is added to 3 times a number the result is 2 less than 4 times the number. The number is?

Answer 1

1) Let the no. be x
therefore, 1/3x=13
x=13X3=39
Therefore, the no. is 39

2)Let the no.be x
therefore, 3x+6=4x-2
3x-4x=-2-6
-x=-8
x=8
therefore, the no. is 8

Answer 2

(1)let the number be 'a'
1/3×a=13
a=13×3
a=39

(2)let the number be 'a'
3a+6=4a-2
6+2=4a-3a
a=8
