1.15x + 1.15y = 24
1.15(x+y) = 24
x+y = 24/1.15
x+y = 20.870
So if you want to solve for y,
y = 20.870 - x
and if you want to solve for x,
x = 20.870 - y
Note that there's no single (x,y) coordinate answer to this question. Since you have two unknowns but only one equation, you have infinitely many possible (x,y) coordinates that will work for the given equation.
Now what specifically was the problem asking for?

Simplifying
1.15x + 1.15y = 24
Solving
1.15x + 1.15y = 24
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1.15y' to each side of the equation.
1.15x + 1.15y + -1.15y = 24 + -1.15y
Combine like terms: 1.15y + -1.15y = 0.00
1.15x + 0.00 = 24 + -1.15y
1.15x = 24 + -1.15y
Divide each side by '1.15'.
x = 20.86956522 + -1y
Simplifying
x = 20.86956522 + -1y

Are you solving for x and y or what? Need more info.

1.15 +1.15 =2.3
24/2.3=10.43
x =10.43
y =10.43
