-2(x-3) = 5x+1

-2x +6 = 5x+1

subtract 5 x from each side

-7x+6 = 1

subtract 6 from each side

-7x = -5

divide both sides by -7

x = -5/-7 = 5/7

x = 5/7

What is the value of X and Y?

Advocard [28]

Answer:

x = 5.25

y = 7.5

Step-by-step explanation:

Since line 1.5 is parallel to line x which is parallel to line y

then 2/(2+5) = 1.5/x

2x = 7(1.5)

2x = 10.5

x = 5.25

Similarly, 2/(2 + 5 + 3) = 1.5/y

2y = 10(1.5)

2y = 15

y = 7.5

I need help on number six I have graphed the data that is given but I need to find three ordered pairs of numbers for each equat

aliya0001 [1]

x-y=-2
y=x+2

Ordered pairs

(0,2)
(1,3)
(2,4)

And

x-y=2
y=x-2

Ordered pairs

(1,-1)
(2,0)
(-2,-4)

Remember parallel lines have no solutions

How do you substitute math 3x+y=-14 and 2x-y=-19 step by step

anastassius [24]

Answer:

x=-33/5 y=29/5

Step-by-step explanation:

Let's solve your system by substitution.

3x+y=−14;2x−y=−19

Solve

3x+y=−14 for y:

3x+y=−14

3x+y+−3x=−14+−3x(Add-3x to both sides)

y=−3x−14

Next is to substitute −3x−14 in for y 2x−y=−19:

2x−y=−19

2x−(−3x−14)=−19

5x+14=−19(Simplify both sides of the equation)

5x+14+−14=−19+−14(Add -14 to both sides)

5x=−33 Dived both sides by 5

5x/5=-33/3

x=−33/5 since you can't dived and a fraction is another form of division you keep it this way.

Step: Substitute -33/5 for x in y=−3x−14:

y=−3x−14

y=−3(-33/5)-14

y=29/5

(Simplify both sides of the equation)(since you can't dived and a fraction is another form of division you keep it this way.)

x=-33/5 and y=29/5

Pls mark brailest this took me a long time to write out lol. Hope this truly helps! Send a heart if so, so I can keep spreading the help!

What is the relationship between the 6s in the number 660,472

scoundrel [369]

Answer:
The first 6 is 10 times greater than the second one

Explanation:
The given number is 660,472
This number can be rewritten as:
660,472 = 600,000 + 60,000 + 400 + 70 + 2

Now, comparing this to the place-value chart shown in the attached image, we would find that:
The first 6 represents the hundred thousands of the number
The second 6 represents the ten thousands of the number
The 0 represents the thousands of the number
The 4 represents the hundreds of the number
The 7 represents the tens of the number
The 2 represents the ones of the number

Now, we are comparing the values of the 6s:
The first 6 represents the hundred thousands of the number
The second 6 represents the ten thousands of the number
This means that:
The first 6 is 10 times greater than the second one

Hope this helps :)
