① ② So a hammer costs 300 Yen and a screw costs 5 Yen. Simultaneous Equations Then just solve the equations. On another day he buys 2 hammers and 40 screws for 800 Yen. Example On one day, a man buys 4 hammers and 10 screws for 1250 Yen. Simultaneous Equations Worded expressions can also lead to simultaneous equations. 15 = 120, strawberry: 8 Yen 4 = 7.2, a balloon has 1.8l of air. 4 = 2 + 5200 ornament: 2600 Yen 4 = 120, he uses 30ml of dye each time.
