The 4,x, y,14and a half in arithmetic progression find x and y

maybe

Step-by-step explanation:

x+y=14 (i)

x−y=4 (ii)

From (ii) y=x−4 ...(iii)

Substituting y from (iii) in (i), we get

x+x−4=14

⇒2x=18

⇒x=9

Substituting x=9 in (iii), we get

y=9−4=5,

i.e, y=5

x=9,y=5

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
