4(2x+3)- 2(4y-1)=30 (5x+1)/3 – (y-3)/4 = 3 To jest uklad rownan. Prosze o jego rozwiazanie. Pilnie i dokladnie !!!!

4(2x+3)-2(4y-1)=30 (5x+1)/3-(y-3)/4=3 8x+12-(-8y)-2=30 (5x+1)-(y-3)/12=34 8x+8y=30-12+2 60x+12-y-3=36 8x+8y=20 60x-y=36-12+3 8x+8y=20 60x-y=27 8x+8y=20 480x-8y=216 ___________ 488x=236 x=0,45 3,6+8y=20 8y=20-3,6 8y=16,4 y=2,05
