Question

5x+2=27
3x-5=2x-3
5x-6=3x+8
-2x-3=x-15
5x=8x-15
4x+1=2
Y-5=3y-25
5x+6=10x+5

Alguien me ayuda? :"³ ​

Answer 1

1. 5x + 2 = 27

5x = 27 - 2

5x = 25

x = 25/5 = 5

2. 3x - 5 = 2x - 3

3x - 2x = - 3 + 5

x = 2

3. 5x - 6 = 3x + 8

5x - 3x = 8 + 6

2x = 14

x = 14/2 = 7

4. - 2x - 3 = x - 15

- 2x - x = - 15 + 3

- 3x = - 12

x = 4

5. 5x = 8x - 15

5x - 8x = - 15

- 3x = - 15

x = 5

6. 4x + 1 = 2

4x = 2 - 1

4x = 1

x = 1/4

7. y - 5 = 3y - 25

y - 3y = - 25 + 5

- 2y = - 20

x = 10

8. 5x + 6 = 10x + 5

5x - 10x = 5 - 6

- 5x = - 1

x = 1/5
