You need to solve a system of equations. you decide to use the elimination method. which of these is not allowed? 3x-2y=7 equation 1 3x+4y=17 equation 2

x = 31/9 and y = 5/3

Step-by-step explanation:

It is given that,

3x - 2y = 7  (1)

3x + 4y = 17 (2)

To find the solution by elimination method

Step 1: Subtract eq(2) from eq(1)

3x - 2y = 7  (1)

3x + 4y = 17 (2)

0  - 6y = -10

6y = 10

y = 10/6 = 5/3

Step 2: Substitute the value of y in eq (1)

  3x - 2y = 7  (1)

  3x  - 2*(5/3) = 7

  3x = 7 + 10/3

  3x = 31/3

   x = 31/9

Therefore x = 31/9 and y = 5/3
