Question

i) 16x - 1 = 12x + 3
i) 3x - 2 = 4x +9
k) 5x - 3+ x = 2x + 9
1) 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

preciso de ajuda ​

Answer 1

Resposta:

a) x=1

b) x= 1

c)x= -3

d)x=2

e)x=5

f)x=1,5

g)x=3,33

h) -2

Explicação passo-a-passo:

a) 16x -1=12x-3

16x-12x=1+3

4x=4

x=4/4

x=1

b) 3x-2=4x+9

3x-4x=2-9

-1= -7

x= -7/-1

x= 1

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

5x-1x-2x=3-9

2x= -6

x= -6/2

x= -3

d) 17x-7x=x+18

17x-7x-1x=18

9x=18

x=18/9

x=2

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

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

4x=20

x=20/4

x=5

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

1x+2x+5x-4x=9-3

4x=6

x=6/4

x=1,5

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

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

6x=20

x=20/6

x=3,33

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

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

4x=-8

x=-8/4

x=-2
