8462-x=762

Answer 1

a)x+1909=2050

=>x=2050-1909

=>x=141

b)x-586=3705

=>x=3705+586

=>x=4291

c)8462-x=762

=>x=8462-762

=>x=7700

Answer 2

x + 1909 = 2050

x = 2050 - 1909

x = 141

x - 586 = 3705

x = 3705 + 586

x = 4291

8462 - x = 762

x = 8462 - 762

x = 7700

Answer 3

x + 1909 = 2050

x = 2050 - 1909

x = 141

x - 586 = 3705

x = 3705 + 586

x = 4291

8462 - x = 762

x = 8462 - 762

x = 7700
