Question

Subtract the following
$\frac{5}{1 + 3x} - \frac{7}{1 + 3x}$
$1 - \frac{2x + 5x}{7x}$
$\frac{9x \times 4y {x}^{2} }{22} - \frac{x {y}^{9} }{22}$
​

Answer 1

 5/(1+3x) - 7/(1+3x)

= (5-7)/(1+3x)

= -2/(1+3x)

 1 - (2x+5x)/7x

= 1 - 7x/7x

= 1 - 1

= 0

 (9x * 4yx^9)/22 - (xy^9)/22

= ((36 x^10 y)-(xy^9))/22

= xy(36 x^9 - y^8)/22
