Question

anyone help!!!!

Answer 1

yes?

Answer 2

help!!Use the substitution method to solve the system of equations. Enter your answer as an ordered pair.

2x - y = 10
3x - 2y = 8 anyone

Answer 3

Isolate one variable first ie. solve one equation for x or y

Answer 4

-_- dont get it totally forgot about this things

Answer 5

2x - y = 10

Add y to both sides: 2x - y + y = 10 + y, sp 2x = 10+y

Divide both sides by 2: 2x/2 = (10+y)/2, so x = (10+y)/2

now substitute (10 + y)/2 in for x and solve

Need more help?

Answer 6

do u have to give points or just a number

Answer 7

Usually "give you answer as an ordered pair" mean write you x first then y so,

(x,y)

Answer 8

k

Answer 9

yes im confuse but anyways thanks for ur help

Answer 10

Ya so, the equation 3x - 2y = 8

Anytime you see an "x" you can now replace it with (10+y)/2

So after you do that it looks like this 3[ (10+y)/2 ] - 2y = 8

Now we have one variable so this is solvable!

Answer 11

omg that looks too much word

Answer 12

i think the answer is 5,3 or 4,6

Answer 13

Its not bad

Distribute the 3: (30 + 3y)/2 - 2y = 8

Common denominator: (30 + 3y)/2 + 2y(2/2), (30 + 3y)/2 + 4y/2, (30 + 3y -4y)/2 = 8

Multiply both sides by 2: 30 + 3y -4y = 16

Combine "like" terms: 30 -y = 16

Subtract 30 from both sides to isolate y: -y = -14

Multiply both sides by -1: y = 14

Answer 14

So, now we know y = 14 so we can take either one of the two equations that are give and plug in 14 for y

So, lets do 2x - y = 10

2x - (14) = 10

Add 14 to both sides: 2x = 24

Divide both sides by two to isolate x: x = 12

Now all we need to do is write our answer as an ordered pair then we are done!

since x = 12 and y = 12 and x goes first then the final answer is

(12,14) where 12 is the x and 14 is the y. (x,y)

Answer 15

whats

Answer 16

crazy man

Answer 17

Its gets much much easier with practice don't worry

Answer 18

-_- i hope uhh

Answer 19

thanks

Answer 20

hey man i need ur help again

Answer 21

Use the substitution method to solve the system of equations. Enter your answer as an ordered pair.

x + y = 11
-x = -y - 9

Answer 22

so u there

Answer 23

Try this one and ask questions as you go

Answer 24

-_- im just here to get answers lol honestly i forgot this freshman stuff even though ur explanations are very good

Answer 25

Well try khan academy.com "solving linear equations"

Answer 26

that doesnt work
