प्रश्न

Solve the following equation and check your result:

4z + 3 = 6 + 2z

योग

उत्तर

4z + 3 = 6 + 2z

On transposing 2z to L.H.S and 3 to R.H.S, we obtain,

4z − 2z = 6 − 3

2z = 3

Dividing both sides by 2, we obtain

`z =  3/2`

L.H.S = 4z + 3 = 4 × `(3/2)` + 3

= 6 + 3

= 9

R.H.S = 6 + 2z 

= 6 + 2 × `(3/2)`

= 6 + 3

= 9

L.H.S. = R.H.S.

Hence, the result obtained above is correct.
