Answer 1

Answer:y=3

Step-by-step explanation:

Step :-solve equation as follows. 3x+2y=-6 then, 3x=-6-2y then,x=-6-2y/3 nowww, step:- put this value of x in another equation and proceed you will get y=2

Answer 2

Answer:

x= -4 and y= 3

explanation:

eq1 * 2= 6x+ 4y= - 12

eq2 * 3= 6x+15y= 21

(-) (-) (-)

on subtraction :-

- 11y = - 33

y= 3

putting value of y in eq1:-

6x+4(3) = -12

6x + 12= -12

6x = - 24

x= -4
