what is y=13-x,solve for x
y=13-x
Add x to both sides.
y+x=13+x-x
combine terms
y+x=13
Now subtract y from both sides.
y-y+x = 13-y
combine terms
x=13-y
In order to solve for x, you must isolate the x. So try to get x on one side.
To solve the equation y = 13 - x for x, you need to isolate the variable x on one side of the equation. Here's how to do it:
Step 1: Start with the equation y = 13 - x.
Step 2: To isolate the variable x, you need to get rid of the "-x" term on the right side of the equation. You can do this by adding x to both sides of the equation. This will cancel out the -x term on the right side.
y + x = 13 - x + x
y + x = 13
Step 3: Now you have the equation y + x = 13. To get x by itself, subtract y from both sides of the equation. This will cancel out the y term on the left side.
y + x - y = 13 - y
x = 13 - y
So, the solution for x is x = 13 - y.
