Question

AYUDA POR FAVOR!!!
doy todos mis puntos corona y corazon AL QUE ME AYUDE​

Answer 1

a) x + 4(2x + 3) = x + 20

   x + 8x + 12 = x + 20

  9x + 12 = x + 20

 8x = 8

x = 8/8

x = 1

b) 4x + 5 - 7x = 2(3x +6) - 1

   -3x + 5 = 6x +12 - 1

  -9x = 11 -5

  - 9x = 6

     x  = -6/9

     x = -2/3

c) 3x +x +5 = 2(10 + 2x) - 5x

   4x + 5 = 20 + 4x - 5x

  4x + 5 = 20 -1x

  5x = 20 - 5

 5x = 15

  x = 15/5

  x = 3

d) 5(x+3) = 4(x+2)

   5x + 15 = 4x + 8

   5x - 4x = 8 - 15

            x = -7

e) 7x + 4(2x - 15) = 3(2 - 5x) - 6

   7x + 8x - 60 = 6 - 15x - 6

   15x - 60 = -15x

   30x = 60

     x = 60/30

     x = 2

f) 2(x-1) + 6x = 4x + 9

  2x - 2 + 6x = 4x + 9

 8x - 2 = 4x + 0

 8x - 4x = 2

  4x = 2

   x = 2/4

   x = 1/2

g) 5(x-1) + 6x = 4x + 9

   5x - 5 + 6x = 4x + 9

   11x - 5 = 4x + 9

   11x - 4x = 9 + 5

   7x = 14

   x  = 14/7

  x =  2

h) x + 3(x-8) = 3(x-1)

  x + 3x - 24 = 3x - 3

 4x - 24 = 3x - 3

 4x - 3x = -3 + 24

          x = 21

i) 5x - 9 = 15 + 2(x+3)

  5x - 9 = 15 + 2x + 6

  5x - 2x = 21 + 9

      3x = 30

       x = 30/3

       x = 10

j) 8x + 2(x-1) - 11 = 5x + 3(x+1)

  8x  + 2x - 2 - 11 = 5x + 3x + 3

  10x - 13 = 8x +3

  10x - 8x = 3 + 13

   2x = 16

     x = 16/2

    x = 8

k) 8x + 2(x - 1) - 11 = 9(x-2) + 8

    8x + 2x - 2 - 11 = 9x - 18 + 8

     10x - 13 = 9x - 10

     10x - 9x = -10 + 13

     x = 3

l) 4x + 2(x-1) = 4x + 3(x+2) + 23

  4x + 2x - 2 = 4x + 3x + 6 + 23

   6x - 2 = 7x + 29

   -2 -29 = 7x - 6x

   -31 = x

m)

  $(\sqrt{2x+6})^2 =(4)^2\\2x+6=16\\2x = 10\\x = 10/2\\x = 5$

n)

$(3x-2)^3=8\\\sqrt[3]{(3x-2)^3} =\sqrt[3]{8} \\3x-2=2\\3x = 4\\x = \frac{4}{3}$

o)

$3x^3-10=14\\3x^3=24\\x^3=8\\x =\sqrt[3]{8} \\x = 2$

p)

$\sqrt{4x}+12=18\\ \sqrt{4x} =6\\( \sqrt{4x})^2 =(6)^2\\4x = 36\\x = 36/4\\x = 9$
