Question

2x + y = -4
-3y = 2x + 12

Answer 1

x = 0 and y = -4

Explanation:

2x + y = -4...................................(i)

-3y = 2x + 12................................(ii)

from (i)

2x+y=-4

=> y=-4-2x

again from (ii)

-3y=2x+12

=> -3(-4-2x)=2x+12

=> 12+6x=2x+12

=> 6x-2x=12-12

=> 4x=0

=> x= 0

now,

y=-4-2(0)

=> y=-4-0

=> y=-4
