Pls help asap, im lowkey struggling hehe tqqq​

Answer 1

Hammer cost 300 yen and screw cost 5 yen

Explanation:

From given statement can be obtain

Hammer = h & screw = s

Eq 1 4h + 10s = 1250 y

Eq 2 2h + 40s = 800 y

Multipyle eq 2 with 2

2 (2h + 40s = 800) =2(800)

⇒ 4h + 80s = 1600 eq 3

Now minus eq 1 from eq 3

4h + 80s = 1600y

4h + 10s = 1250

O + 70s = 350y

s = 350/70

S = 5

To find hammer price put value of s in eq 1

4h + 10s = 1250

4 h = 1250 - 50 = 1200

h = 1200/4 = 300
