Answer:

two solutions

1.x=-7/5;y1=6/5

2.x=-7/5;y2=-6/5

Step-by-step explanation:

y=-2x-4

y=3x+3

-2x-4=3x+3

-5x=7

x=-7/5

y1=14/5-4=(14-20)/5=6/5

y2=-21/5+3=(-21+15)/5=-6/5

Answer:

2 solutions

Y= -6/5, -7/5

Step-by-step explanation:

substitute Y int he first equation with 3x+3 and work it out

3x+3 = -2x-4

x=-7/5

and then use the answer you just got and substitute again and work out till u get answer

y= 3(-7/5) +3

x=-6/5
