so 0.25 pounds cover one square foot0.25/1
542(1+1/4)
542(4/4+1/4)
542(5/4)

15x^2y^3=3*5*x*x*y*y*y
-20x^3yz=-1*2*2*5*x*x*x*y*z
comon numbers are
5,x,x,y
greatest common factor is 5x^2y
-15x=-4x
We know that adding zero wouldn’t change the value
-15x=-4x+0
Now we can add 4x (since that’s the opposite of the negative sign) to the other side
-11x=0
0 divided by 11 is 0
x=0
