Question

1/3+℅2–×=1/2 cual es el valor de x​

Answer 1

Hallar valor de X

7x - 2/3 = 5x + 1/2

2/5x - 2/3 = x - 1/5

(x-3)/2 + (3x+1)/2 = 1

√(3)/2x - x = √(3)/2x + 2

2/x + 3/x = 1/2

2/x-1 + 2/x+2 = 1

Solución

7x - 2/3 = 5x + 1/2

7x - 5x = 1/2 + 2/3

2x = (3 + 4)/6

2x = 7/6

x = 7/12

2/5x - 2/3 = x - 1/5

2/5x = x - 1/5 + 2/3

2 = 5x (x - 1/5 + 2/3)

2 = 5x² - x + 10x/3

5x² - x + 10x/3 - 2 = 0

(15x² - 3x + 10x )/3 = 0

15x² + 7x = 0

x₁ = -7/15

x₂ = 0

(x-3)/2 + (3x+1)/2 = 1

(x - 3 + 3x + 1)/2 = 1

(4x - 2)/2 = 1

2x - 1 = 1

2x = 2

x = 1

((√3)/2)x - x = (√(3)/2)x + 2

((√3)/2)x - (√(3)/2)x - x = 2

-x = 2

x = -2
