hi pls anyone could help me solve this problem and explain me with the model diagram?

3 blouses cost as much as 2 skirts. A shopper spent \$84 on 6 blouses and 3 skirts. How much did 1 blouse and 1 skirt cost altogether?[file]

3 blouses = 2 skirts ------------------------(1)

\$84 = 6 blouses + 3 skirts

since 6 blouses = 4 skirts

therefore

\$84 = 4 skirts + 3 skirts
making each skirt to be \$84/7 = \$12

and that makes

3 blouses = 2 x 12 (from 1)
each blouse works out to be \$8
