Question

por favor necesito ayuda con estas operaciones¿cual es el valor de la incognita ?

d) – 6 – 2x + 3x= – 6

e) x + x +4 +2 = 8

f) 2x + x +5 – 5 = 6

g) 2x – x – 3 – 5 = 2

h) 2x + 2 – 1 – x = 2

i) 5x – 4 –3x = – 2

j) 2x – 5 –x +1 +x = – 6

Answer 1

d) -6-2x+3x = -6

-6+x=-6

x=-6+6

x=0

e) x + x +4 +2 = 8

2x + 6 = 8

2x = 8-6

2x = 2

x = 2/2

x = 1

f) 2x + x +5 – 5 = 6

3x=6

x=6/3

x = 2

g) 2x – x – 3 – 5 = 2

x - 8 = 2

x = 2 +8

x = 10

h) 2x + 2 – 1 – x = 2

x + 1 = 2

x = 2-1

x = 1

i) 5x – 4 –3x = – 2

2x - 4 = -2

2x = -2 + 4

2x = 2

x = 2/2

x = 1

j) 2x – 5 –x +1 +x = – 6

2x -4 = -6

2x = -6+4

2x = -2

x = -2/2

x = -1

Saludos.
