5x + 6= -10 + 7X

5x-7x= -10 - 6

-2X = -10 + (-6)

-2X = -16

X = -16/-2

X = 8

Answer:

x = 8

Step-by-step explanation:

Given

5x + 6 = - 10 + 7x ( subtract 7x from both sides )

- 2x + 6 = - 10 ( subtract 6 from both sides )

- 2x = - 16 ( divide both sides by - 2 )

x = 8

1) Para que valores reais de x o ponto P (3x -6, 2x +4) pertence ao 4º quadrante?
skelet666 [1.2K]

Answer:

There are no real values of x for point P to belong to the 4 quadrant

Step-by-step explanation:

<u><em>The question in English is</em></u>

To what real values ​​of x does the point P (3x -6, 2x +4) belong to the 4th quadrant?

we know that

A point in the fourth Quadrant has the x-coordinate positive and the y-coordinate negative

we have the point

P (3x-6, 2x+4)

3x-6 > 0 ----> inequality A  ( x-coordinate must be positive)

2x+4 < 0 ---> inequality B ( y-coordinate must be negative)

Solve Inequality A

3x-6 > 0

3x > 6

x > 2  -----> (2,∞)

Solve Inequality B

2x+4 < 0

2x < -4

x < -2 ----> (-∞,-2)

The solution of the system is

(-∞,-2) ∩ (2,∞)

therefore

The system has no solution

There are no real values of x for point P to belong to the 4 quadrant
