Question

раскройте скобки (5с+8+9d)*6+3*(4c-2-d)     

(340х+5600у-50)/10

Answer 1

(340x+5600y-50):10=34x+560y-5(83a+24b-62c)*22=1826a+528b-1364c(5c+8+9y)*6+3*(4c-2-y)=30c+48+54y+12c-6-3y=42c+51y+42

Answer 2

(5с+8+9d)*6+3*(4c-2-d) =30c+ 48+54d+12c-6-3d=42c+42+52d

(340х+5600у-50)/10=34x+560y-5
