Please help me solve this linear equation:
\n" ); document.write( "(x-9)^2+y^2=25
\n" ); document.write( "4x-3y=61 --> 3y = 4x-61
\n" ); document.write( "y = (4x-61)/3
\n" ); document.write( "--------------
\n" ); document.write( "Sub for y
\n" ); document.write( "(x-9)^2+((4x-61)/3)^2=25
\n" ); document.write( "Multiply by 9
\n" ); document.write( "9*(x-9)^2 + (4x-61)^2 = 225
\n" ); document.write( "9x^2 - 162x + 729 + 16x^2 - 488x + 3721 = 225
\n" ); document.write( "25x^2 - 650x + 4450 = 225
\n" ); document.write( "divide by 25
\n" ); document.write( "x^2 - 26x + 178 = 9
\n" ); document.write( "x^2 - 26x + 169 = 0
\n" ); document.write( "(x-13)^2 = 0
\n" ); document.write( "x = 13, x = 13
\n" ); document.write( "Why do you call that linear? It's a quadratic.
\n" ); document.write( "4*13 - 3y = 61
\n" ); document.write( "y = -3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
