Question

Rezolvati ecuatiile:
a)2x=8,x apartine lui R; b)8x=2,x apartine lui Q; c)5=3y, apartine lui R; d)3x=0,x apartine lui N; e)x-6=4,x apartine lui N; f)2= -x+2, x apartine lui Z; g)4x+11=20,x apartine lui Q;
h)4x+11=20,x apartine R; i)3x-1= 3x, x apartine R; j) -2x+1=4x+8,x apartine lui R;
k)-2t-3+t=t-2,t apartine lui R/Q.

Answer 1

a)x=4
b)x=2/8=1/4
c)y=5/3
d)x=0/3=0
e)x=10
f)x=0
g)4x=9 => x=9/4
h)x=9/4=2,25
i)ecuatie fara solutii reale
j)-6x=7 => x=-7/6
k)-2t=1 => t=-1/2
