Question

Rezolvati ecuatiile:a) 8x=16; b) 4x-8=0;c) 10-x=2;d)13x-9=4;e)3(x+5)=15

Answer 1

a)8x=16 x=16:8 x=2 b)4x-8=0 4x=8 x=8:4 x=2 c)10-x=2 x=10-2 x=8 d)13x-9=4 13x=9+4 13x=13 x=13:13 x=1 e)3(x+5)=15 x+5=15:3 x+5=5 x=5-5 x=1 Sper ca te-am ajutat!!!

Answer 2

a) 8x=16
x=16 : 8
x= 3

b) 4x-8=0
4x=8+0
4x=8
x=8:4
x=2

c)10-x=2
x=10-2
x=8

d)13x-9=4
13x=9+4
13x=13
x=13 : 13
x=1

e)3(x+5)=15
(x+5)=15+3
(x+5)=18
x=18-5
x=13
