Question

Me ayudarina A resolver estas ecuaciones de Primer Grado

Answer 1

4. 4x-8-10x+30=8x+8-6x-9
-6x+22=2x-1
23=8x
23/8=x

8.-2y-3-{-4y+5[-y+2-3y+1+2y-5]}=-y+4
[-2y-2]
{-4y-10y-10}
{-14y-10}
2y-3+14y+10=-y+4
17y=-3
y=-3/17

Answer 2

4(x-2)-5(2x-6)=8(x+1)-3(2x+3) 4x-8-10x+30=8x+8-6x-9 -6x+22=2x-1 -6x-2x=-1-22 -8x=-23 x=-23/-8 x=23/8   -2y-3-{-4y+5+1+[-y+2-(3y-1)+2y-5]}=-(y-4) -2y-3-{-4y+6+[-y+2-3y+1+2y-5]}=-y+4 -2y-3-{-4y+6+[-2y-2]}=-y+4 -2y-3-{-4y+6-2y-2}=-y+4 -2y-3-{-6y+4}=-y+4 -2y-3+6y-4=-y+4 4y-7=-y+4 4y+y=4+7 5y=11 y=11/5
