From a lamp post four feet away from her, Sandra looks up at a in the sky. Diagonally, that bird is five feet away from her. How high up is the bird.
<span>15x-3y=27
5x+4y=14
multiply (2nd) equation by (3)
15x + 12y = 42
</span>15x - 3y=27
15x + 12y = 42
-------------------substract
-15y = -15
y = 1
15x-3y=27
15x-3(1)=27
15x - 3 = 27
15x = 30
x = 2
so now you have x = 2, y =1
