quero calculos me ajudem por favor hjjjjj

Answer 1

1 - )

$2x - 5 = x + 1 \\ x = 1 + 5 \\ x = 6$

2 - )

$2x + 3 = x + 4 \\ x = 4 - 3 \\ x = 1$

3 - )

$5x + 7 = 4x + 10 \\ x = 10 - 7 \\ x = 3$

4 - )

$5x - 20 = 0 \\ 5x = 20 \\ x = 4$

5 - )

$2x - 16 = 0 \\ 2x = 16 \\ x = 8$

6 - )

$18x - 43 = 65 \\ 18x = 108 \\ x = 6$

7 - )

$4x + 2 = 18 \\ 4x = 16 \\ x = 4$

8 - )

$2x - 5 = x + 10 \\ x = 10 + 5 \\ x = 15$

9 - )

$23x + 2 = 2 \\ 23x = 0 \\ x = 0$

10 - )

$12 - 7 + 4x = 25 \\ 4x = 25 - 5 = 20 \\ x = 5$

11 - )

$5x - 3x = 30 \\ 2x = 30 \\ x = 15$

12 - )

$4x + 10 = 45 - 3x \\ 7x = 35 \\ x = 5$

13 - )

$5x - 5 = 10 \\ 5x = 15 \\ x = 3$

14 - )

$8x - 11 = 4x + 13 \\ 4x = 24 \\ x = 6$

15 - )

$9x - 8 = 37 \\ 9x = 45 \\ x = 5$

16 - )

$2x - 10 + 7x + 10 = 180 \\ 9x = 180 \\ x = 20$

Espero ter ajudado.

Abraços e bons estudos ;-)

Answer 2

1) 2x – 5 = x +1

2x-5-x = 1

x-5 = 1

x = 5+1

x = 6

2) 2x+ 3 = x + 4

2x+3 -x = 4

x+3 = 4

x = 4 - 3

x = 1

3) 5x + 7 = 4x + 10

5x + 7 - 4x =10

x + 7 = 10

x = 10 - 7

x = 3

4) 5x – 20 = 0

5x = 20

x = 20/5

x = 4

5) 2x – 16 = 0

2x = 16

x = 16/2

x = 8

6) 18x - 43 = 65

18 x = 65 + 43

18x = 108

x = 108/ 18

x = 6

7) 4x + 2 = 18

4x = 18 - 2

4x = 16

x = 16/4

x = 4

8) 2x – 5 = x + 10

2x - 5 -x = 10

x - 5 =10

x = 10+5

x = 15

9) 23x + 2 = 2

23x = 2 - 2

23x = 0

x = 0

10) 12 – 7 + 4x = 25

5 + 4x = 25

4x = 25 - 5

4x = 20

x = 20/4

x = 5

11) 5x – 3x = 30

2x = 30

x = 30/2

x = 15

12) 4x + 10 = 45 – 3x

4x + 10 + 3x = 45

7x + 10 = 45

7x = 45 - 10

7x = 35

x = 35/7

x = 5

13) 5x - 5 = 10

5x = 10 + 5

5x = 15

x = 15/5

x = 3

14) 8x – 11 = 4x + 13

8x - 11 - 4x = 13

4x - 11 = 13

4x = 13 + 11

4x = 24

x = 24/4

x = 6

15) 9x - 8 = 37

9x = 37 + 8

9x = 45

x = 45/9

x = 5

16) 2x – 10 + 7x + 10 = 180

9x - 10 + 10 = 180

9x = 180

x = 180/9

x = 20
