Rezolvati in utimea Z ecuatia:
a)(x-12)+(16-2x)=14;
b)(x+25)-(x-12)=13;
c)2x-6=14-2x;
d)(44-x)+(x-35)=0;

Va rog sa aratati cum ati facut nu doar rezultatul.Va rogg!!!!!!

[tex]a) (x-12)+(16-2x)=14\\x-12+16-2x=14\\-x+4=14\\-x=14-4\\-x=10\\ x=-10\\ b) (x+25)-(x-12)=13\\ x+25-x+12=13\\ x-x=13-25-12\\0x=-24\\ x=-24:0\\S= multime vida\\ c) 2x-6=14-2x\\ 2x+2x=14+6\\ 4x=20\\ x=20:4\\x=5\\ d) (44-x)+(x-35)=0\\ 44-x+x-35=0\\ 0x+9=0\\ 0x=-9\\ x=-9:0\\ S= multime vida[/tex]
a) x-12+16-2x=14
X+2x=14+(12+16)
3x=14+28
3x=42/:3
x=42:3
x=14
