Question

Решите уравнение
а)2(2х-1)-3(х-2)=6+4(3-2х)
б)2(х+2)-3(х-2)=5-4(3х-1)

Answer 1

а) 2(2x-1) - 3(x-2) = 6+4(3-2x)
4x - 2 - 3x + 6 = 6 + 12 - 8x 
4x - 3x + 8x = 6 + 12 + 2 - 6
9x = 14 
x = 14/9
б) 2(x+2) - 3(x-2) = 5-4(3x - 1) 
2x + 4 - 3x + 6 = 5 - 12x + 4 
2x - 3x + 12x = 4 - 4 - 6 + 5 
11x = - 1 
x = -1/11
