Answer 2

Answer: x=3 and y=(-2).

Step-by-step explanation:

• Better understanding of algebra is required to solve this problem like addition of two polynomials, substitution method and elimination method.

• This problem is related to solving the linear equations in two variables.

• Given, 5x + 3y=9        (eq.1)

                   2x - 3y=12       (eq.2)

• We can solve this question by elimination method.

• Let's add the above equations,

        5x + 3y + 2x - 3y=9 + 12

     ⇒7x = 21

     ⇒x = $\frac{21}{7}$

     ∴ x = 3

• Putting the value of x in eq.2 and solving

         2x - 3y=12

     ⇒ 6 - 3y=12

     ⇒ -3y = 6

    ∴ y =(-2)

• So, the value of x and y comes to be 3 and (-2).

• Hence, the required answer is x=3 and y=(-2).
