Explanation

4x + 4y = 12 is just a multiple of x + y = 3 → same line.

The equation 4x + 4y = 12 is just a multiple of x + y = 3 (multiply both sides by 4).  

So, both equations represent the same line, meaning they intersect at all points on that line.

Explanation

x:y = 7:8 → multiply both by 5 ⇒ x:y = 35:40  

y:z = 5:6 → multiply both by 8 ⇒ y:z = 40:48  

So x:z = 35:48
