Question

solve 5x - 2 = 3x - 4​

Answer 1

To solve 5x - 2 = 3x - 4

=> 5x - 3x = - 4 + 2

=> 2x = - 2

=> x = $\frac{-2}{2}$

=> x = $\frac{\cancel{-2}}{\cancel{2}}$

=> x = - 1

Hence, the value of x is - 1. But is this value of x is correct?

Let's find out.

Verification

Put the value of x as - 1.

=> 5x - 2 = 3x - 4

=> 5(-1) - 2 = 3(-1) - 4

=> -5 - 2 = - 3 - 4

=> - 7 = - 7

Here, L.H.S = R.H.S

Hence, it is verified.

Therefore, the value of x is - 1.

Answer 2

5x - 2 = 3x - 4​

5x - 3x = 2 - 4

2x = -2

x = -2/2

x=-1

this is the correct answer

hope it helps :)
