Question

Solve the system of equations below.

x-2y=3
2x-3y=9
A. (3,9)

B. (9,3)

C. (-3,9)

D. (-9,3)

Answer 1

Yeah it b
X=9
Y=3
So yeah

Answer 2

Option B is correct

(9, 3)

Explanation:

Given the system of equations:

`x-2y = 3` .....[1]

`2x-3y = 9` ......[2]

Multiply equation [1] by 2 both sides we have;

`2x-4y = 6` .....[3]

Subtract [3] from [2] to eliminate x we get;

`2x-3y-2x+4y = 9-6`

Combine like terms;

`y = 3`

or

y = 3

Substitute in [1] we have;

x-2(3) = 3

x -6 =3

Add 6 to both sides we have;

x = 9

Therefore, the solution for the given system of equations is, (9, 3)
