Question

1- Hallar el valor de x y verificar. (Incluir procedimiento porfavor)
a) 9 . (x+6) + 19 = 181
b) 17 . x – 5 = 5 . (2.x +1 ) -3
c) 3. (x + 2) = 2 . ( x+ 2) + 2
d) 3 . x + 2 . (x-8) = 4 x +1
e) 6 . (3 x -4 )= 5 . (2x+3) + 1

Answer 1

A) 9(x+6)+18=181

9x+9x6+19=181

9x+54+19=181

9x=181-73

9x=108

x=12

B) 17x-5=5(2x+1)-3

17x-5=5x2x+5-3

17x-5-10x=2+5

17x=2+5

x=1

C) 3x+2=2(x+2)+2

3x+2=2x+2x2+2

3x+2=2x+4+2

x+2-2x=6

x-2x=6-2

-x=6-2

-x=4

x=-4

D) 3x+2(x-8)=4x+1

3x+2x+2x(-8)=4x+1

x=1+16

x=17

E) 6(3x-4)=5(2x+3)+1

18x-10x=16+24

8x=16+24

8x=40

x=5
