Question

1) Resolver as equações
A)10x+16=14x+8
B)2(x-3) =-3(x-3)
C)4(5x-3)-64(3-x)-39(12x-4)=96
D)5(5x-3)+6(x+2)=9(x+3)

Answer 1

A) 10x+16 =14x+8
10x-14x=8-16
4x=8
x=8/4
x=2


B)2(x-3) =3(x-3)
2x-6=3x-9
2x-3x=-9+6
x=-3

A)

10x + 16 = 14x + 8
14x - 10x = 16 - 8
4x = 8
x = 8/4 = 2

B)

2*(x - 3) = -3*(x - 3)
5*(x - 3) = 0
5x - 15 = 0
5x = 15
x = 15/5 = 3

C)

4*(5x - 3)- 64*(3 - x) - 39*(12x - 4)= 96
20x - 12 - 192 + 64x - 468x + 156 = 96
-384x = 144
x = -144/384 = -3/8

D)

5*(5x - 3)+ 6*(x + 2)= 9*(x + 3)
25x - 15 + 6x + 12 - 9x - 27 = 0
22x = 30 
x = 30/22 = 15/11
