Question

Me ajudem
a) x-2/3+2x=5x/2
b) x-5/3+3x-1/2=4
c) x-1/5=x-2x-1/3

Answer 1

A-
x-2/3 + 2x = 5x/2

x-2+6x/3 = 5x/2
2x-4 +12x =15x
x= 4.

B -
X-5/3 + 3x-1/2 = 4

x-5+9x/3 -1/2 = 4
2x-10+18x - 3/6 = 4
2x-10+18x-3 = 24
20x=37
x= 37/20.

C-
x-1/5=x-2x-1/3

x-1/5 = -1+3x/3 -2x
x-1/5 = -1+3x-6x/3
3x-3= -5 +15x-30x
18x= -2
x=-2/18
x = -1/9

Espero ter ajudado,bons estudos!
