Answer:
19
Step-by-step explanation:
if the triangles are similar then EG/BC = FG/BD
51/(x+4) = 57/(2x-7) cross multiply expressions
102x - 357 = 57x + 228
102x - 57x = 228 + 357
45x = 585 divide both sides by 45
x = 13
BD = 2x -7 and 13×2 - 7 = 19
A
Find the two intersections of the lines. The value of x of the intersections will satisfy the system of equations.

Answer:
3/10 > 1/5
Step-by-step explanation:
3/10 = 1.5/5
or
1/5 = 2/10
3/10 > 2/10
1.5/5 > 1/5
3y - ( 4y + 19 ) = - 13 ;
3y - 4y - 19 = - 13 ;
- y - 19 = - 13 ;
-y = 19 - 13 ;
-y = 6 ;
y = - 6 ;
Then, x = 4 * ( - 6 ) + 19 ;
x = - 24 + 19 ;
x = - 5 ;
The solution of the system is x = - 5 and y = - 6 ;
