Can you solve this Algebra 2 equation?

Question

-2x+y=6
4x-2y=5

It doesnt look right to me. This is basic but havin geometry last year. I dont remember. Thanks

Oh yeah. You have to use substitution method

Dang I cant vote yet. But yes. That is correct. I knew something wasnt right.

Answer 1

Yo Dude:

Something is wrong with what you copied down on that
there problem...

Solving the first equation for Y
I get Y = 6 + 2x

Then substituting the value I just found for "Y"
into the second equation you get

4X - 2(6 + 2X) = 5
and
4X - 12 - 4X = 5
-12 = 5 (AND THAT AIN'T SO)

ERROR

ERROR

Answer 2

you can use linear combination, substitution, or elimination method.
I will do substitution since you have a faint idea already.

-2x+y=6 - Find out what x or y equals first

y=6+2x - it does not have to be a numerical value!

Now substitute y into the other equation

4x-2y=5
4x-2(6+2x)=5

4x-12-4x=5

Now solve

0x=17
x=0

Now substitute the x vaule in one of the equations to find the
value of y

-2x+y=6
0+y=6
y=6

Now check the other equation with both the x and y value

4x-2y=5
0-12=5

0=17 - wrong

so there is no correct answer!

yea you are right this equation is wrong

Answer 3

take the first equation and solve for one of the variable. Lets do x:
-2x=6-y
x=(6-y)/-2

plug this into the second equation:
4[(6-y)/-2]-2y=5
-2(6-y)-2y=5

i can see from here that the y's are going to cancel, making this problem not possible. are you sure it is written correctly? if so then the answer is not possible

Answer 4

there is no solution . .

to solve this system of equations by substition . . .

solve the first equation for y:
y = 2x +6

then substitute this into the second equation:
4x - 2(2x + 6) = 5
4x - 4x -12 = 5
0x - 12 = 5

since the x's cancel out .. there is no solution . .

Answer 5

-2x+y=6
4x-2y=5

First, get the first to x= form
-2x=6-y
2x=-6+y
x=-3+.5y

substitute in the x= to the 2nd equation
4(.5y-3)-2y=5
2y-12-2y=5
2y's cancel out
-12=5
WHICH IS WRONG

so there is NO SOLUTION
sorry bud

Answer 6

y = 2x + 6
4x - 2( 2x + 6)
4x - 4x - 12 = 5
-12 = 5

NO SOLUTION

Answer 7

-2x+y=6 *2
-4x+2y=12
4x-2y=5
adding
0=17 which isabsurd

Answer 8

you should attempt this heavily in the different case the timber may initiate splintering and then you could not artwork hostile to the grain anymore. as I continuously say, take care and do it incredible.

Answer 9

4x-4x-2y=5x4
20=2y
20*20
2*2
20*2
10
y=10

Answer 10

i dunno...im barely in geometry right now
