Question

a) (3x-4)+(-2x+11)=0. b) (3x-4)-(-2x+11)=0. c) 5x-8-(3x+9)=-(X+2) d) 8+(x-3)=6-(x+8) obs:quero com cálculos

Answer 1

a) (3x -4) + (-2x + 11) = 0
3x - 4 = 2x - 11
x = 15

b)(3x-4)-(-2x+11)=0
3x - 4 = -2x + 11
5x = 15
x = 3

c) 5x-8-(3x+9)=-(X+2)
5x - 8 - 3x - 9 = -x -2
2x - 17 = -x -2
3x = 15
x = 5

d) 8+(x-3)=6-(x+8)
8 + x - 3 = 6 - x - 8
 x + 5 = -x -2
2x = -7
 x = -7/2 ou -3,5
