Question

4x+3(10-10)=10+10 qual o valor de x?

Answer 1

Resposta:

a) 5-2x+3=-8+4x-2

-2x-4x=-2-8-3-5

-6x=-18

-x=-18/6

-x=-3 . (-1)

x=3

b) 5x+3+2x-4+3x+8=-13

5x+2x+3x=-13-8-3+4

10x=-20

x=-20/10

x=-2

c) 2.(x+3)=10

2x+6=10

2x=10-6

2x=4

x=4/2

x=2

d) 4.(x-2)=3x

4x-8=3x

4x-3x=8

x=8

Explicação passo a passo:

Calcule:

-10-5x+4=10+4x-3

-5x-4x=10-3-4

-9x=3

x=3/9

x=0,3

Determine o valor de x:

10-4x+6·16-8x

-4x+8x=6·16-10

4x=96-10

4x=86

x=86/4

x=21,5

Calcule:

5x+6+2x-4-4-9

5x-2x=-4-4-9-6

3x=-23

x=-23/3

x=-7,6

Determine o valor de x:

4(x+3)=20

4x+12=20

4x=20-12

4x=8

x=8/4

x=2

Calcule o valor de x:

3(x+5)=30

3x+15=30

3x=30-15

3x=15

x=15/3

x=3
