Question

Ajutatima va rog dau 70 pct.+ Coroana Daca imi rezolvati corect urmatoarele ecuati.
a) Solutia ecuatiei x+1 supra 3+1 supra 2 = 1 supra6, x∈Q
b) Solutia negativa a ecuatiei { x-3}=4
c} Solutia ecuatiei 3x=11,x∈Z

Answer 1

a)x+1/4/2=1/6
x+1/2=1/6
x+1=2/6
x+1=1/3=》x=1-3/3=》x=-2/3
b)-x+3=-4
-x=-7|×(-1)
x=7
c)3x=11
x=11/3
