Answer:
(x,y) = (6/5, 38)
Step-by-step explanation:
y = y right?
so, you just substitute both of those equations
26+10x = 44-5x
26 -44 = -5x -10x
x = 6/5
then substitute x into ANY of these two equations
let's say we want the second one
y = 44 - 5 × 6/5
y = 38
I'm not sure but I think that first number there might be a 20 and not a 26. If that's true then, solving the same way you'd have
(x,y) = (8/5, 36)
The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k. (i looked up this explanation but not sure if it’s right.. if it’s wrong let me know:) )
