Question

alguem ajuda porfavor
(d 10-5×=6×+8= e) 2× +6=-3×+1=
f) 2×-1+2×=37×​

Answer 1

Resposta:

a) x +4 = 5

   x = 5 -4

   x = 1

b) 4x -15 = 1

    4x = 1 + 15

    4x = 16

      x = 16/4

      x = 4

c) 5x -7 +2x = 7

   5x +2x = 7 + 7

       7x    = 14

         x    = 14/7

         x    = 2

d) 10-5×=6×+8

    -5x -6x = 8 -10

        -11x   = -2

            x   = -2/-11 (-)

            x   = 2/11

e) 2× +6=-3×+1

   2x +3x = 1 -6

       5x    = -5

          x    = -5/5

          x     = -1

f) 2×-1+2×=37

  2x + 2x = 37 +1

       4x    = 38

          x   = 38/4

          x   = 9,5

Answer 2

Resposta:

a) X+4=5

X=5-4

X=1

b) 4X-15=1

4X=1+15

4X=16

X=16/4

X=4

c) 5X-7+2X=7

5X+2X=7+7

7X=14

X=14/7

X=2

d) 10-5X=6X+8

-5X-6X=8-10

-11X=-2

X=-2/-11

e) 2X+6=-3X+1

2X+3X=1-6

5X=-5.(-1)

5X=5

X=5/5

X=1

f) 2X-1+2X=37X

2X+2X-37X=+1

4X-37X=+1

33X=1

X=33/1

X=33
