Respuesta y comprobacion es para hoy ayudaaaaaaaaaaaa
5s+1=3s-4
7f-3=9f+5
3r+7=2f-4
5x-9=3x+6
2p-5=3x+4
x-8=2x-11

Answer 1

5s + 1 = 3s - 4

5s - 3s = - 4 - 1

2s = - 5

s = -5/2

Comprobación

5s + 1 = 3s - 4

5(-5/2) + 1 = 3(-5/2) - 4

-25/2 + 1 = -15/2 - 4

-23/2 = -23/2

7f-3=9f+5

7f - 9f = 5 + 3

-2f = 8

f = 8/-2

f= -4

Comprobación

7f-3=9f+5

7(-4) - 3 = 9(-4) + 5

-28 - 3 = -36 + 5

31 = 31

3r+7=2r-4

3r - 2r = - 4 - 7

r = -11

Comprobación

3r+7=2r-4

3(-11) + 7 = 2(-11) - 4

-33 + 7 = -22 - 4

-26 = -26

5x-9=3x+6

5x - 3x = 6 + 9

2x = 15

x = 15/2

Comprobación

5x-9=3x+6

5(15/2) - 9 = 3 (15/2) + 6

75/2 - 9 = 45/2 + 6

57/2 = 57/2

2p-5=3p+4

2p - 3p = 4 + 5

-p = 9 (-1)

p = -9

Comprobación

2p-5=3p+4

2(-9) - 5 = 3(-9) + 4

-18 - 5 = -27 + 4

- 23 =  -23

x-8=2x-11

x - 2x = -11 + 8

-x = -3 (-1)

x = 3

Comprobación

x-8=2x-11

3 - 8 = 2(3) - 11

-5 = 6 -11

-5 = -5
