resuelve las ecuaciones de primer grado


porfa es para ahorita les doy coronita

2x+8=40

5x+35=65

3x+7=17
0.5x+6=10
0.25x+10=12
0.02x+0.35=1.25
3x=12
7x=30
0.35x=2.45
0.04x=0.36​

Answer 1

Respuesta:

1. x = 16

2. x = 6

3. x = 10/3

4. x = 8

5. x = 8

6. x = 45

7. x = 4

8. x = 30/7

9. x = 7

10. x = 9

Explicación paso a paso:

1. 2x+8=40 => 2x = 32 => x = 16

2. 5x+35=65 => 5x = 30 => x = 6

3. 3x+7=17 => 3x = 10 => x = 10/3

4. 0.5x+6=10 => 0.5x = 4 => x = 8

5. 0.25x+10=12 => 0.25x = 2 => x = 8

6. 0.02x+0.35=1.25 => 0.02x = 0.9 => x = 45

7. 3x=12 => x = 4

8. 7x=30 => x = 30/7

9. 0.35x=2.45 => x = 7

10. 0.04x=0.36 => x = 9

RPTA:

1. x = 16

2. x = 6

3. x = 10/3

4. x = 8

5. x = 8

6. x = 45

7. x = 4

8. x = 30/7

9. x = 7

10. x = 9
