Question

me ajudem nessas pfv pfv pfv

Answer 1

e)x/4 - x/6 =3
3x12 - 2x/12 = 36/12
3x - 2x = 36
x=36

f) 4x - 8 - 2x = x - 2
4x - 2x - x = -2 +8
x=6

g) 2(x+5) - 3(5-x) = 10
2x + 10 -15 + 3x = 10
2x+3x = 10 - 10 + 15
5x=15
x=15/5
x=3

h)x-1/4  -  x-3/6  = 3/1
3(x-1)/12 - 2(x-3)/12 = 36/12
3x-3-2x+6=36
3x-2x=36+6-6
x=36
