Question

If 2 is subtracted from a number and this difference is tripled, the result is 6 more than
the number. Find the number.

Answer 1

Let the number be x And the result we get is y So x-2=y.... 1 x+6=3y.....2 Subtracting 1 from 2 8=2y y=4 Putting the value in 1 equation x=4+2 x=6

Answer 2

let's consider x= number
and y= result
 
So equations formed would be x-2=y------(1)
 and x+6=3y--------------(2)
 Solving equations___
x=y+2
(y+2)+6=3y
y+8=3y
2y=8
y=4
x=4+2
x=6
ANSWER--number is 6 and solution is 4
