Answer:

plzzz give me brainliest ans and plzzzz follow me

Answer 2

Step-by-step explanation:

2x-3y=1

2x=1+3y

x=(1+3y)/2 -eq 1

3x-4y=1

on substituting value of x from equation 1

we get,

3×(1+3y)/2 -4y=1

(3+9y)/2 -4y=1

(3+9y-8y)/2=1

3+y=2

y=-1

on substituting the value of y in equation 1

we get

x=(1+3y)/2

x=[1+3×(-1)]/2

x=(1-3)/2

x=-2/2

x=-1
