Question

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

Answer 1

x = 4 ; y = -1

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
