Question

1)Rezolvati in R ecuatiile:
a) 3(2x-1)-5(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
VA ROG E URGENR!!

Answer 1

a) 6x-3-15x+5=1
-9x=-1
x=1 supra 9

b)4x+8=6x-2+5
-2x=-5
x=5 supra 2

c)Nu se intelege nimic.
d)6z+18-25=10z-5+3z
-7z=2
z=-2 supra 7

e)4t+12-5+10t=6t-1
8t=-9
t=-9 supra 8

f)5x+10-18=2x-10-x
