Question

TALLER 1) Resuelve las siguientes ecuaciones: a) 10x – 6 + 5x = 9x + 2x + 16 b) 6x + 4 = – 4x + 7 c) 16 +7x -5 + x = 11x – 3 - x d) (6 – 2x) –(-4x+6) = (8x + 11) – (3x – 6) e) 3(2x -2) = 2(3x + 9)

Answer 1

a) 10x – 6 + 5x = 9x + 2x + 16

10x + 5x - 9x - 2x = 16 + 6

15x - 11x = 22

4x = 22

x = 22/4

x = 11/2

b) 6x + 4 = – 4x + 7

6x + 4x = 7 - 4

10x = 3

x = 3/10

c) 16 +7x -5 + x = 11x – 3 - x

7x + x - 11x + x = - 16 + 5 - 3

9x - 11x = 5 - 19

- 2x = - 14

x = -14/-2

x = 7

d) (6 – 2x) –(-4x+6) = (8x + 11) – (3x – 6)

[tex]6-2x-\left(-4x+6\right)=8x+11-\left(3x-6\right)[/tex]

6 - 2x + 4x - 6 = 8x + 11 - 3x + 6

12 + 2x = 5x + 17

2x - 5x = 17

- 3x = 17

x = [tex]-\frac{17}{3}[/tex]

e) 3(2x -2) = 2(3x + 9)

6x - 6 = 6x + 18

6x - 6x = 18 + 6

0 = 24
