Answer:
1) I just simply added the numerators because the denominators of both fractions are equal. As the denominators are same , I simply wrote 6 by taking the L.C.M of both denominators.
4)
[tex] \frac{5x - 3}{6} + \frac{x - 9}{6} [/tex]
[tex] = > \frac{5x - 3 + x - 9}{6} [/tex]
[tex] = > \frac{6x - 12}{6} [/tex]
Taking 6 common from numerator,
[tex] = > \frac{6(x - 2)}{6} [/tex]
Cancelling 6 from both numerator & denominator,
[tex] = > x - 2[/tex]
