4 0

Answer:

Step-by-step explanation:

3x-y=-5

y=3x+5

20x-3(3x+5)=4

20x-9x-15=4

11x=19

x=\frac{19}{11}

y=3(\frac{19}{11})+5

y=\frac{112}{11}

How many solutions does the system below have?<br> y=1/2x+1<br> 2y - x = 2
kvasek [131]

Answer:

infinitely many

Step-by-step explanation:

Rewrite these equations as

y = (1/2)x + 1

2y = x + 2

and then solve the second for y:  y = (1/2)x + 1.  Note that these end results are identical.  The two lines coincide; that is, one lies right on top of the other.  Thus, there  are infinitely many solutions.
