You can put this solution on YOUR website! y=2(x-4)+15 and y=15(x+5)-12
set them equal to each other, since they are both equal to y
2x-8+15=15x+75-12
2x+7=15x+63
13x=-56
x=-56/13 ANSWER
check
8 4/13(2)+15=-16 8/13 +15=-1 8/13 or -21/13 on left
15(9/13)-12=135/13-12=10 5/13-12=-21/13 on right
(-56/13,-21/13)
