guys how do i do 2x+5y=10??

Answer 1

You don't even specify what you're supposed to do with it!

I'll take a wild guess and assume that you're supposed to graph the thing. If that's right, there are a couple ways to do it.

The easiest way:
When x=0, then 5y=10, so y must be 2.
Similarly, when y=0, then 2x=10, so x must be 5.
This gives us coordinates (0,2) and (5,0).
Now that you have two points, you can draw a line.
The line containing those two points is the graph of the equation.

Alternate method:
Put the equation into y = mx + b form:
2x + 5y = 10
5y = -2x + 10
y = (-2/5)x + 2
This is slope-intercept form, where the y-intercept is 2
and the slope is (-2/5).

Hope that helps!

Answer 2

When there are two unkowns ( x and y ), you need two equations in order for you to find the values of x and y.

Since there is only one equation (2x + 5y = 10), all you have to do is give values to one unknown and find the value of the other unkown using the equation. Let me show you.

step 1:
let x = 0

2(0) + 5y = 10
5y = 10
y =10/5
y = 2

let y = 0
2x + 5(0) = 10
2x = 10
x =10/2
x = 5

step 2
plot the coordinates (0,2) and (5,0) in a graph

step 3
connect the the two points.
the line will give you the values of x and y.

Answer 3

this should be right.

2x+5y=10
use (-3,-2)-6 jus tell the teacher the math man did it an you will get an A.

ok but for real try
take away 5y from both sides then you end up with
2x=10-5y
then take away 10 from both sides then you get
2x-10=5y then you use
(10,2) that should work

2(10)-10=5(2)
10=10

Answer 4

if u want to find x:

2x + 5y = 10
2x = 10 - 5y
x = (10-5y) / 2
Then subsitute the value of y into this equation.

For y:
5y = 10 - 2x
y = (10-2x) /5
Then, subsitute the value of x into this equation.

Answer 5

2x+5y=10
5y = -2x +10
y = (-2/5)x + 2

Answer 6

to find x:
2x = 10-5y
x = (10-5y)/2

or, to find y:
5y = 10-2x
y = (10-2x)/5

Answer 7

if you want to graph it just give numbers to the x and find the value of y for example:
if x=0 y=2 so the point (0,2) is part of the graph and you can find another point like when x=5 then y=0 and thats another point and just conect the dots

Answer 8

Easy.

Answer 9

2x+5y=10
2x=10-5y
x=(10-5y)/2

2x+5y=10
2(10-5y)/2=10
(20-10y)/2=10
10-5y=10
-5y=10-10
-5y=0
y=0
2x+5y=10
2x+5(0)=10
2x=10
x=10/2
x=5
