Question

What is the proof of number 5?
Given: 4x + 1 = 6x - 2, Prove: x = 3/2
-
(1) 4x + 1 = 6x - 2
(2) 4x + 3 = 6x
(3) 3 = 2x
(4) 3/2 = x
(5) x = 3/2

Answer 1

put the value of x in the given equation & then try to solve u will gt L.H.S.=R.H.S

Answer 2

& it will be the proof that x=3/2

Answer 3

can u do it @jorgesnz ???????????

Answer 4

not really, i don't get it :S

Answer 5

do you mean how do you get from step 4 to step 5?

Answer 6

\[4 \times \frac{3}{2}+1=6 \times \frac{3}{2}-2\]

Answer 7

\[2 \times 3+1=3\times 3-2 \]

Answer 8

6+1=9-2
7=7
L.H.S=R.H.S

Answer 9

hence it is proved that the value of x=3/2 is right

Answer 10

do u gt it now @jorgesnz ?????

Answer 11

@asnaseer No, is to find the reason of number 5

Answer 12

@jiteshmeghwal9 , yeah

Answer 13

nice to hear :)

Answer 14

do you understand each step from 1 to 5?
