Question

add / subtract the following​

Answer 1

Answer:

a) 4/3x + 5/3x

= (4+5) / 3x

= 9/3x

= 3/x

b) 5x/x-1 - 3x/x-1

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

= 2x/x-1

c) x-2/x-1 + x-2/x-1

= (x-2)+(x-2) / x-1

= 2x-4 / x-1

d) 5x-4 / x^2-1 - 5x-3 / x^2-1

= (5x-4) - (5x-3) / x^2-1

= 5x-4-5x+3 / x^2-1

= -1 / x^2-1
