Question

solve for x and y by elimination method,
2x+3y=0 ,
3x+4y =5

Answer 1

Answer:

hii !

Step-by-step explanation:

2x+3y=0

2x=0-3y

x=-3y/2 (Equation 1)

3x+4y=5

3(-3y/2)+4y=5 (value of x from eq1)

-9y/2+4y=5

(-9y+8y)/2=5

-y=5×2

y=-10

2x+3y=5

2x+3(-10)=5

2x-30=5

2x=5+30

x=35/2

x=17.5

x=17.5

y=-10
