Rezolvati in În ecuatiile: a)8x=16 b)8x-4=0 c)10-x=2 d)13x-9=4 e)3(x+5)=15 f)4x+5=3(x+1)+7 g)8x+2=3(x+1)+4x. Varooog ajutatima

Answer 1

a) x=16/8 =2
b) 8x=4 => x=4/8 =1/2
c) x=8
d) 13x= 4+9 => x= 13/13 =1
e) x+5 = 15/3 = 5 => x= 0
f) 4x+5 = 3x+3+7 => 4x-3x = 3+7-5 => x= 5
g) 8x+2 =3x+3+4x => 8x-3x-4x = 3-2 => x=1 ❤❤❤
