Question

Solve by writing the equation for three times a number and 5 subtracted from it gives 16

Answer 1

let the number be x

then the equation will be

3x-5=16 so,

3x=16+5

3x=21

therefore x=21/3

x=7

Answer 2

Three times a number =3x

when five is subtracted from it= 3x - 5

It gives 16

so the equation is

3x-5=16

=> 3x=16 +5

=> 3x=21

=> x =21/3

=> x= 7

so, the value of x is 7.
