answered by Derp 
In your first one, you already have a common denominator, so just (5x  7)/(x+3)
#2, 6/(x+7)  3/(x2) , notice I put in the brackets, they are essential
LCD = (x+7)(x2)
= ( 6(x2)  3(x+7))/((x+7)(x2))
= (6x123x21)/((x+7)(x2))
= (3x  33)/((x+7)(x2))
do the last two using exactly the same steps, only the numbers change 👍
