Question

find equations of x and y x+2y=8 and 3x+2y=12

Answer 1

Here is the answer for your question.

Answer 2

Answer:

x=2 and y=3

Step-by-step explanation:

x+2y=8.....1

3x+2y=12......2

multyplying equation 1 by2 and equation 2 by 2,we get

(x+2y=8)*2

(3x+2y=12)*2

2x+4y=16...3

6x+8y=24....4

from equation 3 and 4,we get

6x+8y=24

2x+4y=16

4x = 8

x=2

now,

putting the value of x=2 in equation 1,we get

x+2y=8

2+2y=8

2y=8-2

2y=6

y=6/2

y=3

therefore, x=2 and y=3
