The area of a circle is pi times its radius squared, or A = pi*(r)^2.  The radius of a circle is one half of the length of its diameter, or r = (1/2)*d.  Solving the first equation for r, we get    r^2

Hi Brittanie,    You can solve systems of equations having fractions in the same way as ones that have whole numbers.  For example, you can write the two equations as:    (1/3)X + (1/2)Y = -4    (3/3)X

2009-10-11 algebra trouble with a seemingly easy question!!:

Hi Saaketh,    SQRT(2x+7) - x = 2    add x to both sides    SQRT(2x+7) = x+2    Square both sides    2x + 7 = x^2 + 4x + 4     subtract (2x+7) from both sides    0 = x^2 + 2x - 3    factor the right side
