jim_thompson5910 · Answer

y = x + 5

-5x-1 = x + 5 ... plug in y = -5x - 1

now solve for x

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).

x + 5 = -x - 1
    +1          +1
x + 6 = -x
-x          -x (?)

6 = -2 x?

anonymous · Answer

or -x = 3?

jim_thompson5910 · Answer

well it's not x = -3, it should be x = -1

so this suggests that there is only one solution
