Answer :

We have the Linear Equation as follows:

4x + 7 = x + 2


4x-x = 2-7(transpose x to LHS and 7 to RHS)


3x = -5



x is equal to which is neither a fraction nor an integer.


Option(a) is incorrect because:


Explanation


We have the Linear Equation as follows:


3x + 2 = 5x + 2


3x-5x = 2-2(transpose 5x to LHS and 2 to RHS)


-2x = 0




Here x is 0 and it is an integer.


Option (b) is incorrect because:


Explanation


We have the Linear Equation as follows:


4x-18 = 2


4x = 2 + 18 (transpose 18 to RHS)


4x = 20



x = 5


Here x is 5 and it is an integer.


Option (d) is incorrect because:


Explanation


We have the Linear Equation as follows:


5x-8 = x + 4


5x-x = 8 + 4(transpose x to LHS and 8 to RHS)


4x = 12



x = 3


Here x is 3 which is an integer.
