Question

x+2x+3-5x=4x-9
5x+6x-16=3x+2x-4

4x+6-2x=(x-6)+10+14

Answer 1

Olá, Paty32!

x+2x+3-5x = 4x - 9
3x - 5x - 4x = -9 - 3
3x - 9x = -12
-6x = -12
x = -12 / -6
x = 2

5x + 6x - 16 = 3x + 2x - 4
5x + 6x - 3x - 2x = -4 + 16
11x - 5x = 12
6x = 12
x = 12 / 6
x = 2

4x + 6 - 2x = (x-6) + 10 + 14
4x + 6 - 2x = x - 6 + 10 + 14
4x - 2x - x = -6 + 10 + 14 - 6
2x - x = 4 + 8
x = 12

Answer 2

A) x + 2x + 3 - 5x=4x - 9

3x - 5x + 3 = 4x - 9

- 2x + 3 = 4x - 9

- 2x - 4x = - 9 - 3

- 6x = - 12

x= - 12/-6

x= 2

B) 5x + 6x-16=3x + 2x - 4

11x - 16 = 5x - 4

11x - 5x = - 4 + 16

6x = 12

x= 12/6

x= 2

C) 4x + 6 - 2x=(x- 6) + 10 + 14

2x + 6 = x - 6 + 24

2x + 6= x + 18

2x -x= 18 - 6

x= 12
