y = tulips

x + y = 13

1.25x + .90y = 14.85

-1.25x - 1.25y = -16.25

1.25x + .90y = 14.85

-0.35y = -1.40

y = 4 tulips

x + 4 = 13

x = 9 lillies

(9 lillies, 4 tulips)

Solve each equation. check your solution. <br> -1/2x-7=-11
cupoosta [38]
I'll offer you a deal in return for your 5 points:  I'll solve it . . . . You check it.

<u>-1/2x - 7  = -11</u>

Add  7  to each side:            -1/2 x  =  -4

Multiply each side by  2 :      - x  =  -8

Multiply each side by  -1 :     <em> x  =  8</em>

Take it Allalala !

It all depends upon what other things are given If hypotenuse is not given, in cosine or reciprocals are useless. In that case only tan and cot will be equally convenient if adjacent sides are given.
