Question

How many solutions does this system have?

y = x + 5
y = –5x – 1

one
none
infinite
two

Answer 1

y = x + 5

-5x-1 = x + 5 ... plug in y = -5x - 1

now solve for x

Answer 2

2nd method is..plot the graph of both functions (straight lines ) intersection points will be the solution .. You can solve any qu. of this type by plotting graph. ( clearly two straight lines can intersect only at one point so your ans . is one).

Answer 3

x + 5 = -x - 1
+1 +1
x + 6 = -x
-x -x (?)

6 = -2 x?

Answer 4

or -x = 3?

Answer 5

well it's not x = -3, it should be x = -1

so this suggests that there is only one solution
