Question

cuanto es 60x-1=3(1+12x)

2x+3(2x-1)=x+67

3(x+4)=4x+1

-3x=2x+4x-x

porfavor con despeje

Answer 1

Respuesta:

a-

$60x - 1 = 3(1 + 12x) \\ 60x - 1 = 3 +36x \\ 60x - 36x = 3 + 1 \\ 24x = 4 \\ x = 4\div 24 \\ x = 0.166666667$

b-

$2x + 3(2x - 1) = x + 67 \\ 4 {x}^{2} - 2x + 6x - 3 = x + 67 \\ 4x^{2} + 4x - 3 = x + 67 \\ 4 {x}^{2} 4x - x = 67 + 3 \\ 4x^{2} + 4x - x=70 \\ 4 {x}^{2} + 3x = 70$

c-

$3(x + 4) = 4x + 1 \\ 3x + 12 = 4x + 1 \\ 12 - 1 = 4x - 3x \\ 11 = x$

d-

$- 3x = 2x + 4x - x \\ 2x + 4x - x + 3x \\ 8x = 0$
