eric is ten years younger than leslie. in ten years, he will be ten years more than one-half as old as leslie. find their present age.
\n" ); document.write( "==============================================================
\n" ); document.write( "Let L = Leslie's present age
\n" ); document.write( "Then Eric's age = L - 10
\n" ); document.write( "In 10 years Leslie's age will be L + 10 and Eric's age will be (L-10) + 10 = L
\n" ); document.write( "Since in 10 years Eric will be 10 more then 1/2 of Leslie, we can write
\n" ); document.write( "L = 1/2(L+10) + 10
\n" ); document.write( "Solve for L:
\n" ); document.write( "L = L/2 + 15
\n" ); document.write( "L = 30
\n" ); document.write( "Leslie's age = 30
\n" ); document.write( "Eric's age = 20
\n" ); document.write( "
