Question

resuelve las siguientes ecuaciones a. 4(x-8)=6(x+2) b. 3(x+4)-2 (x+1)=4(x+4) c. 2(x-4)+4(2x-3)= 2(x+4) d. 3(x-1)-3(2x-3)= 4(x+4)-2(2x-1)

Answer 1

Respuesta:

a. 4(x-8)=6(x+2) === 4x - 32 = 6x + 12 === -32 -12 = 6x - 4x === -44 = 2x === -22 = x

b. 3(x+4)-2 (x+1)=4(x+4) === 3x + 12 - 2x -2 = 4x + 16 === x + 10 = 4x + 16 === 10 - 16 = 4x - x === -6 = 3x === -2 = x

c. 2(x-4)+4(2x-3)= 2(x+4) === 2x - 8 + 8x - 12 = 2x + 8 === 10x -20 = 2x + 8 === 10x - 2x = 8 + 20 === 8x = 28 === 2x = 7

d. 3(x-1)-3(2x-3)= 4(x+4)-2(2x-1) === 3x -3 - 6x + 9 = 4x + 16 - 4x +2 === -3x + 6 = 18 === 6 - 18 = 3x === -12 = 3x === -4 = x
