The solution of the equation 3x – 4 = 1 – 2x is ______.
उत्तर
The solution of the equation 3x – 4 = 1 – 2x is 1.
Explanation:
Given, 3x – 4 = 1 – 2x
⇒ 3x + 2x = 1 + 4 ...[Transposing –2x to LHS and –4 to RHS]
⇒ 5x = 5
⇒ `(5x)/5 = 5/5` ...[Dividing both sides by 5]
∴ x = 1
Hence, the solution of the given equation is 1.
