Question

Verify whether x=3, y= -1 is the solution of the given simultaneous linear equations.

2x-3y = 9 and x +y = 2b
pls give the answer fast....wrong answer will be spamed​

Answer 1

Answer:

Yes

Step-by-step explanation:

Let,

2x-3y=9 ------------------------------------ i)

x+y=2 ----------------------------------------ii)

Multiplying eqn ii) by 2

2x-2y=4 -------------------------------------iii)

Now, subtracting i )from iii)

2x+2y=4

-(2x-3y)=-9

5y=-5

y=-1

Now, placing the value of y in eqn i), we get,

2x-3(-1)=9

2x+3=9

2x=9-3

x=6/2

x=3

Therefore, x=3 and y=-1 is the solution.
