let p time in minutes speaking Polish
let h time in minutes speaking Hungarian
p + h = 5 equation 1
190 p - 150 h = 370 equation 2
multiply eq. (1) by 150 (both sides)
15 0p + 150 h = 750
190p -150 h = 370
add the two eqiations we get :
190 p + 150p = 370 + 750
340 p = 1120
p= 1120/ 340 = 3.29
3 minutes speaking Polish and 2 minutes speaking Hungarian.
make sure if the number 370 ?? i think it is wrong , it can be 270 because i get a point in the answer
