Question

daca puteti sa ma ajutati si voi o sa va ajut

Answer 1

b)
5x/2 -4 = 6- 7x/3
5x/2 +7x/3 =10
15x+14x=60
29x=60
x=60/29

c) √3x-3=2√3x
√3x=-3
x=-3/√3=-√3

e)21x-5-(24x-7)=0
21x-5-24x+7=0
3x=2
x=2/3

g) √7-(-√7+x)-x=0
√7+√7-x-x=0
2x=2√7
x=√7

i)3(x-2)+2(x-3)=5x-12
3x-6+2x-6=5x-12
3x-6+2x-6=5x-12
5x=5x
x poate lua orice valoare

b)x(x-2)=1+(x-3)x
x²-2x=1+x²-3x
-2x=1-3x
x=1

proba
1(1-2)=1+(1-3)×1
-1=1-2
-1=-1
