Question

From the two regression equations y = 4x - 5 and 3x=2y+5, find x and y​

Answer 1

Answer:

it's easy the first mark as brain list let me slove

Step-by-step explanation:

y=4x-5

3x=2y+5

so first let put y in 2nd equation

3x=2(4x-5)+5

3x=8x-10+5

3x=8x-5

3x-8x= -5

-5x= -5

x= -5/-5

x=1

Now y

so put x answer in y one

y=4x-5

y= 4(1)-5

y=4-5

y= -1

This is the answer take a lot of effort mark as brain list and thanks my answer

Plz thank you so much

Answer 2

Answer:

equation s can be written as:

4x - y = 5.......(í)

3x - 2y = 5......(ii)

by elimination method,

multiply equation 1 by 2,

therefore,

8x - 2y = 10

3x - 2y = 5

= 5x = 5 ( 2y gets canceled)

x = 1

putting in equation (I)

4(1) - y = 5

y = 5 - 4

y = 1
