Step-by-step explanation:
y=-2x-4
y=3x+3
-----------
-2x-4=3x+3
-2x-3x-4=3
-5x-4=3
-5x=3+4
-5x=8
x=8/-5
y=-2(-8/5)-4
y=16/5-4
y=16/5-20/5=-4/5
 
                                
             
                    
              
              
                
                
Answer:
x=-8/5, y=-4/5. (-8/5, -4/5).
Step-by-step explanation:
y=-2x-4
y=3x+3
-----------
-2x-4=3x+3
-2x-3x-4=3
-5x-4=3
-5x=3+4
-5x=8
x=8/-5
y=-2(-8/5)-4
y=16/5-4
y=16/5-20/5=-4/5

Answer:
n = 2/9
Step-by-step explanation:
switch sides: 63n=14
divide both sides by 63: 63n/63 = 14/63
simplify: n = 2 / 9
