Question

a,2+x=10 b.3x=-30 c,29x+4)=16 d,-3(2x+4)=5-(x+10 e,4x-2(x-5)=3(2x-10 f,2x+4=x+10 g,5x+10 -3x=8x-5+10? Me podem ajudar Por favor ?

Answer 1

a) 2-2+x=10-2,    x = 10 - 2,   x = 8
b) 3x=-30,     x = -30 / 3,   x = -10
c) 29x+4)=16,   29x = 16 - 4,   29x = 12,   x = 12/29
d) -3(2x+4)=5-(x+10,     -6x - 12 = 5 - x - 10,        -6x +x = 12 + 5 - 10
-5x = 17 - 10,     -5x = 7(-1)     x = -7/5
e) 4x-2(x-5)=3(2x-10,    4x -2x + 10 = 6x - 30,    4x - 2x - 6x = -30 -10
-4x = -40 (-1),   4x = 40,      x = 40/4,      x = 10
