c)8x+4=6x+10
d)4/5+x\2=x/3-1
e)x+15=25

Obs* eu já fiz só queria saber se fiz certo só n fiz a letra a me ajudem

Answer 1

a)x/3+x/2=1
2x/6+3x/6=1
5x=1
x=1/5
b)4(x+3)=3(x+7)
4x+7=3x+21
4x-3x=21-7
x=14
c)8x+4=6x+10
8x-6x=10-4
2x=6
x=3
d)4/5+x/2=x/3-1
24/30+15x/30=10x/30-30
15x-10x=-30-24
5x=-54
x=-54/5
e)x+15=25
x=25-15
x=10
