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.
