Question

RESOLVA AS EQUACOES ABAIXO:
10x+16=14x+8=
2(X -3)=-3(X -3)=
4(5X -3) -64(3 -X)-3(12X -4)=96=
5(X+1)+6(X+2)=9(X+3)=

Answer 1

a) 10x-14x = -16-8
-4x = -20
x = 20/4
x = 5

b) 2x-6 = -3x +9
2x + 3x = 9+6
5x = 15 
x = 15/5
x = 3

c) 20x-12-192+64x -36x +12 =96
20x+64x-36x = 96 +12+192-12
48x = 288
x = 288/48
x = 6

d) 5x+5+6x+12 = 9x+27
5x+6x-9x = 27-5-12
2x = 10
x = 10/2
x = 5
