Question

if 2 X + 3 Y is equals to minus 5 and 3 X + 3 Y is equals to 16 has a unique solution then find p​

Answer 1

Answer:

2x+3y=-5......1

3x+3y=16......2

Subtracting the equation 1 & 2

2x+3y=-5

3x+3y=16

- - -

-x =-21

Substitute x=-21 in the equation 1

2(-21)+3y=-5

-42+3y =-5

3y =-5+42

3y =37

y =37/3

(-21,37/3)is the solution of the given equation
