Question

Rezolvati urmatoarele ecuatii:a)x + 2.174=5.074;b)x - 1.079 =32.105;c)19.703 - x = 8.347;d)2.173 + x + 11.437 = 25.719;e)210 + 147 = x + 319;f)1.973 + (x - 73)= 2.135.

Answer 1

a)x + 2.174=5.074; x= 5.074-2.174; x=2.900

b)x - 1.079 =32.105;x=32.105+1.079; x=33.184

c)19.703 - x = 8.347; x=19.703-8.347; x=11.356

d)2.173 + x + 11.437 = 25.719;  x= 25.791-(2.173+11.437);  x=12.181

e)210 + 147 = x + 319;

f)1.973 + (x - 73)= 2.135.
