Question

2x+3y=0,3x+4y=5 by substitution method find x and y

Answer 1

Answer:

$x = 15$

$y = - 10$

this is a answer

Answer 2

Answer:

Step-by-step explanation:

2x+ 3y =0 ---------------1

3x+ 4y =5----------------2

now multiply 1 by 3 and 2 by 2 and then subtract

6x+9y=0

-6x-8y=-5

--------------

y=-5

now put the value of y in equation 1 we get x

2x = 0 -3y

2x = -3(-5)

2x = 15

x = 15/2

x= 7.5
