State all integer values of x in the interval (-3, 3] that satisfy the following
Galina-37 [17]

(-3,3] is an interval which means that -3 and 3 are not inclusive of the values of x -5/3.

We have given

-3x+4 > 9

Required values of x.

State the values of x within -3 and 3.

subtract 4 from both sides,

-3x+4-4>9-4

<h3>What is the meaning of like terms?</h3>

like terms are terms that have the same variables and powers. The coefficients do not need to match.

Collect Like Terms

-3x > 5

(-3x)(-1)   <   5(-1)

3x  <  -5

Divide both sides by 3

3x/3 < -5/3

x    <   -5/3

(-3,3] is an interval which means that -3 and 3 are not inclusive of the values of x is -5/3.

What’s the answer to this question? I’m confused as to how to do this.
choli [55]

Answer:

x = 20

Step-by-step explanation:

(3x + 50) = (6x - 10)

Subtract 6x on each side

3x + 50 - 6x = -10

Combine the x values together

-3x + 50 = -10

Subtract 50 on each side

-3x = -60

Divide each side by -3

x = 20
