Rozwiąż i sprawdź równania: 35x-18+43=2x+15+23x= 3y-7+4-6y-13+3y=5y-4+18-2y= Bardzo mi to potrzebne

35x-18+43=2x+15+23x 35x-2x-23x =15+18-43 10x = -10 /:10 x= -1 3y-7+4-6y-13+3y=5y-4+18-2y 3y-6y+3y-5y+3y= -4+18+7-4+13 -2y = 38 /(-2) y= -19 pozdrawiam;)

35x-18+43 = 2x+15+23x 35x+25 = 25x+15 35x-25x = 15-25 10x = -10 |:10 x = -1 sprawdzenie: L = 35*(-1)-18+43 L = -35+25 L = -10 P = 2*(-1)+15+23*(-1) P = -2+15-23 P = 13-23 P = -10 L = P 3y-7+4-6y-13+3y = 5y-4+18-2y -16 = 3y+14 3y = -16-14 3y = -30 |:3 y = -10 sprawdzenie: L = 3*(-10)-7+4-6*(-10)-13+3*(-10) L = -30-7+4+60-13-30 L = -33+17 L = -16 P = 5*(-10)-4+18-2*(-10) P = -50-4+18+20 P = -54+38 P = -16 L = P
