Question

Rezolvati in R ecuatiile:

a) 7-5(x-3)/8=2 ;

b)x/3 + x-1/2=x/2 ;

c) 3y+1/4 + 5y-3/3=y+1/6 - 1 ;

d)2z+5/3 + 5z-4/7 - 3 =0 ;

e) x+5/2 + x+1/6 = 1/9 ;

f) 2(x+1)=3(x-5)+7​

Answer 1

Răspuns:

a)7-5*(x-3)/8=2

x=7-5*3/8=2

x= 7-15/8=2

x=7-1.8=2

x=6,8=2

b)x/3+x-1/2=x/2

3x=3+1-2=x/2

3x=4-2=x/2

3x=2=x/2

3x=1x

x=3-1

x=2
