Answer:

3x - 4

---------

10(x + 3)

Explanation:

x -2 x - 3

----------- ( - ) ----------

2x + 6 5x + 15

Multiply both sides by the denominator

5(x - 2) 2( x - 3)

----------- ( - ) ----------

5(2)(x + 3) 2(5)(x + 3)

multiply the numbers together

5x - 10 2x - 6

----------- ( - ) ---------

10(x + 3) 10(x + 3)

Subtract the numberator

5x - 10 - (2x - 6)

5x - 10 - 2x + 6

5x - 2x = 3x

-10 + 6 = -4

3x - 4

3x - 4

----------

10(x + 3)

I hope this helps!
