Question

ME DEEM O PROCESSO DE CADA CALCULO PFV

Answer 1

Explicação passo-a-passo:

i) 16x - 1 + 1 = 12x +3 + 1

16x = 12x +4

16x - 12x = 12x - 12x + 4

4x = 4

4x/4 = 4/4

x = 1

j) 3x - 2 = 4x + 9

3x - 2 + 2 = 4x +9 +2

3x = 4x +11

4x +11 = 3x

4x - 3x = -11

x = -11

k) 5x - 3 + x = 2x + 9

5x -2x + x = 9+3

4x = 12

x = 12/4

x = 3

l) 17x - 7x = x +18

10x -x = 18

x = 18/9

x = 2

m) 2x - 4 = 18 - 2x

4x = 18+4

x = 22/4

x = 5,5

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

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

(-6x = -12 ) -1

6x = 12

x = 12/6

x = 2

o)11x - 16 = 5x - 4

11x -5x = -4 + 16

6x = 12

x = 12/6

x = 2

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

5x -3x + 2x = 0

x = 0
