Question

L) 17x - 7x = x + 18
m) x + x - 4 = 17 - 2x + 1
n) x + 2x + 3 - 5x = 4x - 9
o) 5x + 6x - 16 = 3x + 2x - 4
p) 5x + 4 = 3x - 2x + 4​

Answer 1

Explicação passo-a-passo:

L) 17x - 7x = x +18

10× - x = 18

9x = 18

x = 18/9

x= 2

M) x + x - 4 = 17 - 2x + 1

2x + 2x = 18 + 4

4x= 22

x = 22/4

x = 5,5

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

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

- 6x = -12 .(-1)

6x = 12

x = 12/6

x = 2

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

11x - 5x = 16 - 4

6x = 12

x= 12/6

x= 2

P) 5x + 4 = 3x - 2x + 4

5x - x = 4- 4

4x = 0

x= 0/4

x= 0
