Option A
ANSWER:
In the equation, 3x+7(x + 1) = 2(6x + 5) -2x ,no solution exists for “x”
SOLUTION:
Given equation is 3x + 7(x + 1) = 2(6x + 5) − 2x
By multiplying the terms within the bracket, we get
3x + 7x + 7 = (2)6x + (2)5 – 2x
On simplifying the above equation, we get
3x + 7x + 7 = 12x +10 -2x
10x + 7 = 10x + 10
By moving the terms from right side to left side, we get
(10x -10x) + (7 – 10) = 0
0 + (-3) = 0
-3 = 0

Hence the given equation is invalid for any value of x
So, there is no solution, which satisfies the given equation.
