Question

4x+7 y
3x+2y-5
x-y
if x=3,y= 2 find the value of the following​

Answer 1

Answer:

4x + 7y = 26

3x + 2y - 5 = 8

x - y = 1

Answer 2

Answer:

3x−2y=5.. (1)

3y−2x=3

−2x+3y=3

Multiply (1) by 2 & eq (2) by 3

6x−4y=10..._Adding eqn (3) and (4), we get

6x−4y=10−6x+9y=19___________5y=1

y=51

Putting the value in 

6x−54=10

6x=10+54=554

x=5×654=59

x=59

Now x+y=59+51=5
