Question

Solve: 2x + 5y = -1
3x + 2y = 4

Answer 1

x = 2, y = -1

(x,y) = > (2,-1)

Explanation:

2x + 5y = -1

3x + 2y = 4

-3(2x + 5y = -1) = > -6x - 15y = 3

2(3x + 2y = 4) = > 6x + 4y = 8

-6x - 15y = 3

6x + 4y = 8

-11y = 11

/-11 /-11

y = -1

2x + 5y = -1

2x + 5(-1) = -1

2x -5 = -1

+5 +5

2x = 4

/2 /2

x = 2

(x,y) = > (2,-1)

Hope this helps!
