Solve the system of equations below.
x-2y=3
2x-3y=9
a. (3,9)

b. (9,3)

c. (-3,9)

d. (-9,3)

Option B is correct

(9, 3)

Step-by-step explanation:

Given the system of equations:

         .....[1]

      ......[2]

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

              .....[3]

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

Combine like terms;

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)

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
