I think elimination method means, add or subtract two equations in a way that it cancels a term out.
E. G.
Add the two equations,
x = y + 3
y= - 4x - 3
x+y = (y+3) + (-4x-3)
x+y = y - 4x
x=-4x
x=0
To find out Y using elimination method,
Muliply 4 to the first equation, and then subtract the second equation from the first.
4x = 4y +12
y= -4x - 3
4x-y = (4y+12) -(-4x-3)
4x-y = 4y + 4x + 15
-y = 4y + 15
-5y = 15
y = - 3
Hope this helps. Thanks

I saw the figure of the fishpond. It composed of a rectangle and a circle. The circle is cut into two and each half is attached to the width of the rectangle making an oblong shaped fishpond.
Length of the rectangle: 2.5 inch
Width of the rectangle and diameter of the circle: 1 inch
1/2 inch equals 15 feet.
2.5 inches = 75 feet
1 inch = 30 feet
Area of a rectangle = 75 ft * 30 ft = 2,250 ft²
Area of a circle = 3.14 * (15ft)² = 3.14 * 225ft² = 706.50 ft²
Total Area = 2,250 ft² + 706.50 ft² = 2,956.50 ft²
