Question

3x+2y=10 5x-2y=22 need the answers to x and y

Answer 1

Answer:

x = 4 ; y = -1

Step-by-step explanation:

3x + 2y = 10         ------------(I)

5x - 2y = 22 -------------(II)

Add both the equation and y will be eliminated and we can find the value of x

(I)       3x + 2y = 10

(II)      5x - 2y = 22     {Now add}

         8x        = 32

                 x = 32/8

x = 4

Plugin x = 4 in equation (I)

3*4 + 2y = 10

12 + 2y = 10

      2y  = 10 - 12

       2y = -2

         y = -2/2

y = -1
