Answer:

x=4

Step-by-step explanation:

3(3x+4)=-2(4-2x)​

9x+12=-8+4x

taking value of x at left side we get

9x-4x=-8-12

5x=-20

divide by 5 at both side

5x/5 =20/5

simplify then

x=4

Answer:

x=4/13 =0.307

Step-by- step explanation

3(3x+4)=-2(4-2x)​

9x+12=8-4x

taking value of x at left side we get

9x+4x=8-12

13x=-4

divide by 13 at both side

13x/13 =4/13

What is the classification of each system? Drag the answers into the boxes to match each system. {4x−2y=102x−y=5 {y=2x−3−2x y=−5
Rus_ich [418]

1.   4x − 2y = 10 and 2x − y = 5

Lines are coincident.

2.  y = 2x − 3 and −2x + y = −5

Lines are parallel.

3.  2x − 5y = 14  and 3x + 4y = 10

Lines are intersecting.

<h2>Linear system</h2>

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

<h3>Given</h3>

1.   4x − 2y = 10 and 2x − y = 5

2.  y = 2x − 3 and −2x + y = −5

3.  2x − 5y = 14  and 3x + 4y = 10

<h3>Condition for the lines.</h3>

\rm \dfrac{a_1}{a_2} \neq  \dfrac{b_1}{b_2} \ \ \ \ \ \ \ \ \ \ \ Lines\ are\ intersecting\\\\\rm \dfrac{a_1}{a_2} = \dfrac{b_1}{b_2} \neq  \dfrac{c_1}{c_2}\ \ \ \  Lines \ are\ parallel\\\\\rm \dfrac{a_1}{a_2} = \dfrac{b_1}{b_2} = \dfrac{c_1}{c_2} \ \ \ \  Lines\ are\ coincident

<h3>Drag the answers into the boxes to match each system.</h3>

1.   4x − 2y = 10 and 2x − y = 5

Lines are coincident.

2.  y = 2x − 3 and −2x + y = −5

Find three consecutive odd intergers whose sum is 219
Agata [3.3K]

Answer:

1st odd = 71

2nd odd  = 73

3rd odd  = 75

Step-by-step explanation:

As numbers are consecutive odd so let:

1st odd = x

2nd odd = x + 2

3rd odd = x + 4

According to given condition:

x + x +2 + x + 4 = 219

Adding like terms

3x + 6 = 219

Subtracting 6 from both sides

3x + 6 -6 = 219-6

3x = 213

Dividing both sides by 3

x = 213/3

x = 71

So the numbers will be:

1st odd = x = 71

2nd odd = x + 2 = 71 + 2 = 73

3rd odd = x + 4 = 71 + 4 = 75

Proof:

1st odd + 2nd odd + 3rd odd = 219

71 + 73 + 75 = 219

219 = 219

Hence proved!

I hope it will help you!
