Answer 1

Answer:

90

Step-by-step explanation:

let the number be x

then, according to question,

(2/3)x =x-30

multiply the lhs and rhs by 3

2x= 3x-90

x=90

Answer 2

Answer:

90

Step-by-step explanation:

Let the number be : X

Equation : 2/3 * ,,  = x-30

                  2x/3    = x-30

               2x/3 ( - ) x = -30  [ By bringing x to the other side)

                (LCM=3)

               2x/3 ( - )  3x/3   =  -30

                           -x/3        =  -30

                            -x          =  -30 × 3

                            -x         =    -90

                             x         =      90          ( By cancelling minus from both sides)
