Question

**Help plzzz I give medals**
3x+4y=18
x+3y=11
Make a table of values for each linear equation. Include at least three rows of the table. Be sure to label each table.

Answer 1

Before we can sub numbers in, rearrange the equations to be of the form y = ....

Answer 2

is it 3

Answer 3

No, I'll do the first one for you:
3x+4y=18
4y=18-3x
y=(18-3x)/4

Do the same for the second equation then we can get going with the table.

Answer 4

what did u do, u just put the number and didn't tell me what u did

Answer 5

Answer 6

No, I rearranged the first equation to make it of the form y=....

Answer 7

Do the same for the second equation

Answer 8

dont know how to

Answer 9

Don't know how to, or don't want to? This is very basic algebra.

Answer 10

dont know

Answer 11

y=9/2=3x/4

Answer 13

Okay, let's work through my example for the first equation:
3x+4y=18 (initial equation)
4y=18-3x (subtract 3x from both sides)
y=(18-3x)/4 (divide both sides by 4)

We've gone from a horrible equation, to a nice one of the form y=...

Now do the same for x+3y=11

Answer 14

y=11/3-1/3x

Answer 15

Answer 16

Yes!

Answer 17

Okay, so now we have our two equations:
y=(18-3x)/4
y=(11-x)/3
Let's plug in values of x and see what values of y come out:
