Question

1)Rezolvati in R ecuatiile:
a) 3(2x-1)-5(3x-1)=1
3x-1)=1
b) 4(x+2)= 2(3x-1+5
c) 3(y+4)-(-3+y)x (-2)=3
d) 6(z+3)-25=5(2z-1)+3z
e)4(t+3)-5(1-2t)= 6t-1
f)5(x+2)-18=2(x-5)-x

Answer 1

Am atasat rezolvarile

Answer 2

a)6x-3-15x+5=1
-9x=1-2|(-1)
9x=1
x=1/9
b)4x+8=6x-2+10
4x-6x=0
-2x=0
x=0
c)3y+12-6x+2xy=3
cred că nu ai copiat ex corect
d)6z+18-25=10z-5+3z
6z-13z=20-18
-7z=2
z=-2/7
e)4t+12-5+10t=6t-1
14t-6t=-8
8t=-8
t=-1
f)5x+10-18=2x-10-x
5x-2x+x=-10+8
4x=-2
x=-1/2
