Question

hallar el valor de X:
a)4X+2=1

b)18= 3X

c)2 X+3 X= 15

d)6X4= 10
​

Answer 1

4x + 2 = 1

4x = 1 - 2

4x = - 1

x = - 1/4

Sustituimos los valores =

4x + 2 = 1

4( - 1/4) + 2 = 1

- 4/4 + 2 = 1

- 1 + 2 = 1

1 = 1

18 = 3x

18 / 3 = x

6 = x

Comprobamos =

18 = 3x

18 = 3(6)

18 = 18

2x + 3x = 15

5x = 15

x = 15 / 5

x = 3

Comprobamos =

2x + 3x = 15

2(3) + 3(3) = 15

6 + 9 = 15

15 = 15

6x + 4 = 10

6x = 10 - 4

6x = 6

x = 6 / 6

x = 1

Sustituimos valores =

6x + 4 = 10

6(1) + 4 = 10

6 + 4 = 10

10 = 10

Saludossss, un fuerte abrazooo!!.
