5 (2x - 5) = -25

2 ( x + 8 ) = 40 - x

6 (3x - 2) = 24

3 ( 2x - 5) = 45 + 4x

9 (3x - 7) = 18

3 ( 8x - 2) = 4 (5x + 6)

4 (x - 9) = - 16 4 (x - 2) = 12 - x

Answer 1

Respuesta:

5 . (2× - 5 ) = - 25

10×-25= - 25

10×=0

×=0/ 10

×=0

6. (3× - 2) =24

18× - 12 = 24

18 × = 36

× = 36 × 18

× = 12

9. (3× - 7 ) = 18

27 × - 63 = 18

27 × = 81

× = 81 / 27

×=3

2. (× +8) = 40 - ×

2× + 16 = 40 - 16

3× = 24

× = 24 / 3

× = 8
