ax & bx both are integer than the sum will be integer as well.
ax + bx = (a+b)x
Option C can be the only answer.
x, a, b all can be non integer as well.
take a = 4 = b & x = \(\frac{1}{2}\) - Option B is wrong
take a = \(\frac{1}{2}\) = b & x=4 - Option A is wrong
Answer C
ax + bx = (a+b)x
Option C can be the only answer.
x, a, b all can be non integer as well.
take a = 4 = b & x = \(\frac{1}{2}\) - Option B is wrong
take a = \(\frac{1}{2}\) = b & x=4 - Option A is wrong
Answer C
