25. Two rectangular plots of land are equal in area. The length of the first plot is one and a half
times its width. The length of the second plot is
7 metres less than three times its width
(a) Denoting the width of the first plot by
x metres and the width of the second plot
by y metres, derive a relation between
and y.
(b) If y = x + 1, calculate the values of
x and y.​

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
