Now, find the value of x by considering the given equation,=7 – 5x = 5 – 7x

Transposing 7 to RHS and it becomes -7 and -7x to LHS it becomes 7x

= 7x – 5x = 5 – 7

= 2x = -2

Multiplying both side by (1/3)

= 2x × (1/2) = -2 × (1/2)

= x = (-2/2)

= x = -1

By substituting -1 in the place of x in given equation, we get

LHS,

= 7 – 5 × (-1)

= 7 – (-5)

= 7 + 5

= 12

RHS,

= 5 – 7 × (-1)

= 5 – (-7)

= 5 + 7

= 12

By comparing LHS and RHS

= 12 = 12

∴ LHS = RHS

Hence, the result is verified.
