Question

Resolva as equações:

A)5(2X1-)=3(X-4)
B)6(3X-2)=2(X-6)
C)7(2X+2)=8(3X-1)
D)3(3X-1)=6(4X-8)

Answer 1

A) 5(2x1) = 3(x-4)

10x + 5 = 3x -12

10x - 3x= -12 -5

13x= 17

x= 17/13

B) 6 (3x-2)= 2( x-6)

18x -12= 2x - 12

18x - 2x = -12 +12

16x= 0

x= 0

C) 7( 2x +2) = 8( 3x -1 )

14x +14= 24x-8

14x -24x= -8 -14

-10x = -22 (-1)

10x= 22

x= 22/10

D) 3( 3x -1) = 6( 4x -8)

9x -3 = 24x -48

9x - 24x= -48 +3

15x= -45

x= -3
