this is a pythagorean theorem problem. 24 is the whole ladder, and if you draw it out, is a hypotenuse. 8 is a leg.  a^2+ b^2 = c^2. so 8^2 + b^2 = 24^2

b^2 = 512, so b = sqrt(512) = 22.6

jeka94

Answer:

X=1/6 Y=0

Step-by-step explanation:

If Y= 6x-1, substitute Y on the first equation

7x+3(6x-1)=7/6

7x+18x-3=7/6

25x=(7/6)+3

25x=25/6

x=1/6

Then substitute X on the second equation

Y=6(1/6)-1

Y=0
