ayuda porfavor es para hoy​

Answer 1

Explicación paso a paso:

reduzca las siguientes expresiones:

a) 4x + 3x = 7x

B) 5x - x = 4x

c) -3a + 8a = 5a

d) -7b - 2b = -9b

e) 2x - 1 + 6x - 5 = 8x - 6

f) -4a + 8 - 5a - 6 = -9a + 2

g) 7x - 2x - 3x - 11 = 2x - 11

CALCULE LAS SIGUIENTES OPERACIONES:

a) 4x (-5) = -20x

B) 10x ÷ (-5) = -2x

c) -6a (2) = -12a

d) -9y ÷ (-3) = 3y

e) 2( x + 7) = 2x + 14

f) (10a - 4) ÷ 2 = 5a - 2

g) -3(x - 5) = -3x + 15

h) (9x + 27) ÷ (-3) = 3x - 9

RESUELVE LAS SIGUIENTES ECUACIONES:

a) x - 3 = 5

x = 5 + 3

x = 8

b) -4 + x = 1

x = 1 + 4

x = 5

c) x + 9 = 11

x = 11 - 9

x = 2

d) 7 + x = -2

x = -2 - 7

x = -9

e) ⅓x = 5

x = 5(3)

x = 15

f) -x/5 = 6

x = 6(-5)

x = -30

g) 3x = 18

x = 18/3

x = 6

h) -7x = 21

x = 21/-7

x = -3

i) 2x + 8 = 10

x = 10 - 8/2

x = 2/2

x = 1

j) -3x + 6 = -3

x = -3 - 6/-3

x = -9/-3

x = 3

k) x/4 + 2 = 4

x = (4 - 2)(4)

x = (2)(4)

x = 8

l) x/2 - 8 = -3

x = (-3 + 8)(2)

x = (5)(2)

x = 10

m) 3x = x + 4

3x - x = 4

2x = 4

x = 4/2

x = 2

n) 6x = -20 + 2x

6x - 2x = -20

4x = -20

x = -20/4

x = -5

o) x = -5x + 2

x + 5x = 2

6x = 2

x = 2/6

x = 1/3

x = 0.333

AHÍ ESTÁN TODAS RESUELTAS,SALUDOS,DAME CORONA.
