Question

1) 3-x=2x-6
2) 5x-2=7x+12
3) 5x+2=3x+8
4) 2x+5(3x-1)= x - 13
5) 4x+2(x+3)=2(x+2)​

Answer 1

SOLUCIÓN:

1.-

3-X = 2X - 6

3 +6 = 2X + X

3 = 3X

3/3 = X

1= x

2.-

5x-2=7x+12

5x - 7x = 12 + 2

- 2x = 14

x = 14/ -2

x = -7

3.-

5x+2=3x+8

5x - 3x = 8 - 2

2x = 6

x = 6/2

x = 3

4.-

2x+5(3x-1)= x - 13

2x + 3x - x = -13 - 5 +1

5x - x = -18 + 1

4x = - 17

x = -17/ 4

x = 4, 25

5.-

4x+2(x+3)=2(x+2)

4x+2(x+3)=2x + 4

4x + x -2x = 4 - 2 - 3

5x - 2x = 2 - 3

3x = - 1

x = -1/ 3

x = - 0, 33

De nada
