on my TI 83 calculator how i find answer to x+3y=6?

Question

when i do it says error:window range

Answer 1

well use algebra to get it to 3y = -x+6 then divide by 3 to get
y = (-1/3)x + 2. to enter this into your ti83, the top right button should say y=, type this into the first one in there. Then you should be able to click the top right button ( graph) to look at the function or to find certain points on it.

Answer 2

Hi,
Perhaps the easiest way is to use the solver, but it's a personal choice as to whether you use the solver or the grapher. In either case you must first solve for y.
x+3y = 6
3y= -x +6
y =-x/3+2

Using the Solver:
1) Press MATH, 0 (that's zero not O) and if "EQUATION SOLVER" is not displayed press the up arrow.
2) Enter -x/3 +2 being sure to use the key (-) for the minus.
3) Press ENTER and enter a number for a guess. Zero is okay.
4) Press ALPHA, SOLVE (that's the ENTER key), and your answer will be displayed.

Use the Grapher:
1) Press the Y= button (top left) and clear any equations from the entries.
2) In the Y1 position, enter the equation as in the above example and press GRAPH.
3) Press ZOOM, 4 (for ZDecimal) and then press TRACE.
4) Move the cursor until the Y= at the bottom right of the screen reads Y=0. The corresponding value of X=6 displayed at the bottom left of the screen is the answer.

Hope this helps.

Answer 3

There is actually no "answer" but a set of x and y values that are paired according to your equation.
To get a view of them you can:
First solve for y:
3y = -x + 6
y = -x/3 + 2
press the y= button
put -x/3 + 2 in an open place for y
Note: in entering -x be sure to pree the (-) key not the - key. You cannot lead a line with subtraction.
All othe y values need to be cleared or "turned off"
If the equal is highlighted, has a black box behind it, it can be "turned off" by putting the curser over the = sign and pressing enter.
If you press zoom then 6 you will have an appropriate window for the graph.
If you would like a table of y values for positive integer x values, press 2nd window and set the table to start at 0, with ∆ Tbl = 1 and Indt: Auto and Depend: Auto
Now press 2nd Graph

Answer 4

There are too many variables. You need to know either x or y to solve this.
