Find the nonzero scale for a and b Ax2bxby40 Find the nonzer

Solution

A(x-2)-bx+b(y-4)=0

Open the brackets by multiplying the desired numbers:

Ax - 2A - bx + by -4b = 0

Taking x and y common, we get:

(A - b)x + by - (2A + 4b) = 0

Now putting x= 0, we get:

by = 2A + 4b

And by putting y= 0, we get:

x = (2A + 4b) / (A - b)
