Question

2x+(3-6x)=-17
2(x+1)=3(x-1)​

Answer 1

Salutare!

a)

3 - 6x = 2 - 4x

-6x + 4x = 2 - 3

-2x = -1

x = -1 / -2

x = 1/2

b)

2x + (3 - 6x) = -17

2x + 3 - 6x = -17

2x - 6x = -17 - 3

-4x = -20

x = -20 / -4

x = 20 / 4

x = 5

c)

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

2x + 2 = 3x - 3

2x - 3x = -3 - 2

-x = -5

x = -5 / -1

x = 5

Answer 2

1) 2x + (3 - 6x) = -17

3 - 6x = -17 - 2x

3 - 6x + 17 + 2x = 0

20 - 4x = 0

20 = 4x

x = 5

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

2x + 2 = 3x - 3

2x + 2 - 3x + 3 = 0

-x + 5 = 0

-x = -5

x = 5

3) 3 - 6x = 2 - 4x

3 - 6x - 2 + 4x = 0

1 - 2x = 0

1 = 2x

x = $\frac{1}{2}$

Sper că te-am ajutat ;)
