Question

rezolvati urmatoarele ecuatii a)x+2174=5074 b)x-1079=32105 c)2173+x+11437=25719
d)210+147=x+319 e)1973+(x-73)=2135

Answer 1

a) x=5074-2174=> x=2900.
b) x=32105-1079=> x=31026.
c) 2173+x=25719-11437=>x=14282-2173=> x=12109.
d) x=(210+147)-319=> x=357-319=> x=38.
e) x-73=2135-1973=> x-73=162=> x=162+73=> x=235.
