Find all possible ordered pairs that satisfy a linear equation

I am trying to find all possible combinations of X and Y that satisfy the following linear equation:

f = ((X*25)+(Y*(24))) == 100

The variables should only be evaluated in the following range:

1 ≤ X ≥ 7 and 0.1 ≤ Y ≥ 3 or put another way X = 1:0.01:7 and Y = 0.1:0.01:3

I assume there are multiple simple ways to solve this using either for loops or syms approaches.

The ‘all possible’ criterion would produce infinite solutions. I suspect you would spend the rest of your life calculationg it!

Here is a slightly more limited calculation —

B = 1;
k = 1;
while (B>=0.1) & (B<=7)
    X(k,:) = k/10;
    B = (100 - X(k,:)*25)/24;
    Y(k,:) = B;
    k = k+1;
end
Result = table(X,Y)

Result = 40×2 table
