Question

If 3x – 2y = 0, 3y - 2x = 3 , then find the value of ( x + y ).
​

Answer 1

Answer:

the answer is 3

Step-by-step explanation:

given equations are

3x-2y=0................. equation 1

-2x +3y=3.................. equation 2

by solving equations 1&2

we get,

x=6/5

y=9/5

x+y=6/5+9/5

x+y=15/5

x+y=3

Answer 2

Answer:

x + y = 3

Step-by-step explanation:

The two equetion is,

3x - 2y = 0 ----(1)

3y - 2x = 3 ----(2)

From equation (1) we get,

3x-2y = 0

3x = 2y

x = 2y/3 ---(3)

From equation (2) we get,

3y-2x = 3

-2x = 3 - 3y

x = 3y-3/2 ----(4)

From equation (3) and (4) we get,

2y/3 = 3y-3/2

4y = 9y - 9

4y - 9y = -9

5y = 9

y = 9/5

Substitute y = 9/5 in equation (1) we get,

3x-2y = 0

3x-2(9/5) = 0

3x-18/5 = 0

3x = 18/5

x = 18/5/3

x = 6/5

So, x+y = 9/5+6/5

= 9+6/5 = 15/5 = 3

So, x+y = 3 [Ans.]

I hope it may help you.
