Question

3x=15 - 2x find the value of x
​

Answer 1

Answer:

x=15

Step-by-step explanation:

3x = 15-2x    

3x-2x = 15  (move 2x to L.H.S.)

x=15  

Answer 2

Solution-

3x = 15-2x

or, 3x+2x = 15 { -2x is moved to L.H.S }

or, 5x = 15

or, x = 15/5

or, x = 3  { on dividing 15 by 5, we get 3}

Hence, the value of x is 3.

Verify-

3x = 15-2x

or, 3×3 = 15-(2×3)    {taking x as 3}

or, 9 = 15-6

or, 9 = 9

Hence, L.H.S is equal to R.H.S.
