Question

X - 2y = 5 -3x + 2y = 7 A.x=3, y=-1 B.x = 11, y = 12 C.x=-6, y =- D. x= 3, y=1

Answer 1

The answer is A

3 - 2(-1) = 5

-3(3) + 2(-1) = 7

Answer 2

Answer:

$x=-6,y=-5.5$

Step-by-step explanation:

Given Equations:

               $x - 2y = 5$   equation:1

           $-3x + 2y = 7$   equation:2

Adding equation:1 and equation:2

     $x - 2y+(-3x + 2y) = 5+7\\\\ x-2y-3x+2y=12\\\\-2x=12\\\\x=-\frac{12}{2}\\\\ x=-6$

Putting value of 'x' in equation:1

                     $x - 2y = 5$

                   $-6-2y=5\\\\-2y=5+6\\\\-2y=11\\\\y=-\frac{11}{2} \\\\y=-5.5$

$x=-6,y=-5.5$
