Question

A number is 3 less than three times another number and their sum is 19 then find the number​

Answer 1

Answer:

x+(3x-3)=19

4x=19+3

x=22/4

x=11/2

Answer 2

Answer:

let the another no. is x

so, the no. will be 3x - 3

and

x + (3x - 3) = 19

x + 3x - 3 - 19

4x = 19 + 3

X = 22/4

3x - 3 = 3.22/4 - 3 = 66/4 - 3 = 33/2 - 3 = 33 - 6/2 = 27/2
