+%28+%28x%2B4%29%2F%287%29+%29+%2B+%28+%2815-x%29%2F%2812%29+%29+

Lowest common denominator of 7 and 12 is 84.

+%28+%2812%28x%2B4%29%29%2F%2884%29+%29+%2B+%28+%287%2815-x%29%29%2F%2884%29+%29+
+%28+%2812x%2B48%29%2F%2884%29+%29+%2B+%28+%28105-7x%29%2F%2884%29+%29+
+%28+%2812x%2B48%29%2B%28105-7x%29+%29%2F%2884%29+
+%285x%2B153%29%2F%2884%29+

Here you go.
