Answer 2

723-446=901-624
1+275=823-547
248+398=903-257
487-169=872-554
322+508=121+709
632-291=136+205
543-201=579-237

×+(643-284)=607
x+359=607
x=607-359
x=248

x-(159+266)=340
x-455=340
x=340+455=795

x+(800-647)=729
x+153=729
x=729-153=576

x-(654+290)=56
x-944=56
x=56+944=1000

127+346-x=92+92
473-x=184
x=473-184=289

923-738+x=328+313
185+x=641
x=641-185=453

739+257-x=832-303
996-x=529
x=996-529=467

347+576-x=900-122
925-x=778
x=925-778=147
