Question

Q3. The point at which the pair of equations 4(x+y)= 256 and 256(x-y)= 4 will be intersect

​

Answer 1

Answer:

The pair of equations will intersect at point (x,y) = (32,32)

Step-by-step explanation:

Let's write down the equations below:

4x + 4y = 256................i)

256x - 256y = 4................ii)

Let's eliminate y by multiplying i by 64 and adding to ii.

We have:

256x + 256y = 16384..................iii

256x - 256y = 4............................iv

Adding we have:

512x = 16388

x = 32.007, approximately 32

Substituting to get the value of y we have:

4 × 32 + 4y = 256

128 + 4y = 256

4y = 256 - 128

4 y = 128

y = 32

The pair of equations will intersect at point (x,y) = (32,32)
