15 + 2X = 3 + 5X
\n" ); document.write( "Subtract 2X from each side
\n" ); document.write( "15 = 3 + 3X
\n" ); document.write( "Subtract 3 from each side
\n" ); document.write( "12 = 3X
\n" ); document.write( "Divide each side by 3
\n" ); document.write( "4 = x
Prove it:
\n" ); document.write( "When 15 is added to twice a number (15+8=23), the result is the same as when 3 is added to 5 times the number (3+20=23).
