Sweaters were $5 each, shirts $3, pairs of socks $1. She spent $70 and bought 26 items. She bought 1 more shirt than she did sweaters. Ignoring tax, set up a system of equations and solve the system.

\n" ); document.write( "Sweaters were $5 each, Let this number be x
\n" ); document.write( "She bought 1 more shirt than she did sweaters.
\n" ); document.write( "shirts $3, : this will be x+1
\n" ); document.write( "Balance pair of socks = 26 - ( sum of shirts & sweaters)
\n" ); document.write( "pairs of socks $1.: this will be 26-(x+x+1)
\n" ); document.write( "=26-(2x+1)
