How do you solve this.? I need a genius!!

yes it is homework but Im super confused and I forgot my math book at school so I can't look it up. thanks! 2y-6=3x or y=3x+4

2y - 6 = 3x and y = 3x + 4. Since y = 3x + 4, substitute (3x + 4) into the first problem in place of y.
This gives you 2(3x + 4) - 6 = 3x --> 6x + 8 - 6 = 3x --> 6x + 2 = 3x. Then get all the Xs on one side. 2 = 3x - 6x --> 2 = -3x. Divide each side by -3 to find out what x equals. x= -2/3. now you can find y. y=3x+4 --> y=(3 * -2/3) +4 --> y= -2 + 4 --> y= 2

What are you lookin for

Report as
Not really sure. She just gave me this problem to do.

Solve for x in one of the equations then plug the answer into x in the other equation and solve for y

Report as
Alrighty ! I'll try it thanks!!

Are u looking for the simplified answer of the multiplied one

Report as
Yeah. Think so. Pretty sure. Yes:)
Report as
Which one??
Report as
Sorry I meant wait never mind
Report as

This is confusing I doin math hw now I'll try it :)

Report as
Okay:)
Report as
Sorry I didn't get it :( I'm only in alge 1 I think
Report as
That's okay! Thanks for trying:)

Are you solving for x or y just isolating the variable and then simplifying as mush as possible?

Report as
Yup!!
Report as
then you would work in reverse order of PEMDAS adding and subtracting to Isolate the variable. For example that 1st problem you would add six to each side to cancel out adding the six.
so 2y=3x+6
then divide both sides by two so y=(3x+6)/2
then simplify the right using the distributive property so it would be y=1.5x+3
hope that helps

Are you solving a system of equations?
If you are, then do what hockeychic said.

Report as
Alrighty. Thanks!
Report as

Are you solving for y? Are these two different problems or one?

Report as
Yeah there 2 different ones
Report as
If you take the second equation and plug into the first equation for y, you get x=-2/3. Then if you plug -2/3 in for x into the equation you get y=2. X=-2/3 and y=2. That's if the problem is suppose to be done that way.

2y-6=3x 1) y=mx + b basic form y intercept. If in y intercept form start graph at b then do m=slope.

Report as
Okay! Thank you!:)
Report as
How come no thumbs up for me hmmm?
Report as
There are..
Report as

Plug in 3x+4 for Y in the equation on the left then solve for x

Report as
Okkkay!
Report as

X=2/3

Report as
Okay.. Thanks! I'll solve it and see if I get that!:)

Find what y and x stands for

Report as

you need to know if you are solving for x or y then follow your pemdas rules

Report as

2y-6=3x ------------ eq. 1
y=3x+4 multiply each side by 2. 2y=6x+8 - --------- eq. 2

subtract equation 1 from equation 2

2y=6x+8
2y-6=3x
--------------------
6 = 3x + 8
3x = 6 -8 = -2
divide each side by 3
x = -2/3

substitute x = -2/3 in y=3x+4
y = 3 * -2/3 + 4
y = -2 +4 = 2

(x, y) = (-2/3 , 2)
