Answer:

x = 6

Explanation:

The angle bisector divides the sides proportionally.

(6x -1)/42 = (10x +5)/78

13(6x -1) = 7(10x +5) . . . . . . . multiply by 546 = LCM(42, 78)

78x -13 = 70x +35 . . . . . . . . eliminate parentheses

8x = 48 . . . . . . . . . . . . . . . . add 13-70x

x = 6 . . . . . . . . . . . . . . . . . divide by 8
