Question

va rog ajutatima cu ecuatia 12*(x+1)-4*(x+1)=40
si cu ecuatia 13*(2*x+4)-5*(2*x+4)=48

Answer 1

dai factor comun paranteza si o sa vina:
(2*x+4)(13-5)=48⇒
2*x+4=48-8=40⇒
2*x=40-4=36⇒
x=36/2=18

Answer 2

a)12x+12-4x-4=40
8x+8=40
8x=40-8
8x=32
x=32:8
x=4
b)26x+52-10x-20=48
16x+32=48
16x=48-32
16x=16
x=16:16
x=1
