Explicație pas cu pas:

[(20+339:3+d:4)x7-5x400]:3-22x3+125x8=1000

[(20+339:3+d:4)x7-2000]:3-22x3+125x8=1000

[(20+339:3+d:4)x7-2000]:3-66+125x8=1000

[(20+339:3+d:4)x7-2000]:3-66+1000=1000

[(20+339:3+d:4)x7-2000]:3-66=1000-1000

[(20+339:3+d:4)x7-2000]:3-66=0

[(20+339:3+d:4)x7-2000]:3=0+66

[(20+339:3+d:4)x7-2000]:3=66

[(20+339:3+d:4)x7-2000]=66x3
[(20+339:3+d:4)x7-2000]=198

[(20+113+d:4)x7-2000]=198

[(133+d:4)x7-2000= 198

(133+d:4) x7=198+2000

(133+d:4)x7=2198

133+d:4=2198:7

133+d:4=314

d:4=314-133

d:4=181

d=181x4

d=724
