Remember, you can do anything to an equation as long as you do it to both sides
times both sides by -1
7-5x=2x
add 5x both sides
7=7x
divide both sides by 7
1=x
x=1
Solve this using standard form of ellipse equation:
<span>(x−h<span>)^2</span>/<span>a^2</span>+(y−k<span>)^2</span>/<span>b^2</span>=1.
</span><span>Put the center of the ellipse at (0,0), then h=k=0, so that simplifies things. If the span is 112 feet, then the semi-major axis in the x direction is 56, that would be 'a'
I think you have to use the given information to solve for 'b.'
</span><span>Getting 13.5488, so 13.5 or 13.55 feet seems fine as a rounded answer.</span>
