Rearranging the first equation gives:

Substituting this into the other equation gives:

If x=-1:

So
x=-1, y=-5
The answer is 170. First you add base one and base two divide by twi the multiply that by the height. 18+22=40 40/2=20 20•8.5=170
Answer:
infinite solutions
Step-by-step explanation:
2x-6 = 3x+1-X-7
Combine like terms
2x-6 = 3x-x +1-7
2x-6 = 2x -6
subtract 2x from each side
-6 = -6
Since this is a true statement, x can be any real number
The formula for the law of sines is:
sin(A)/a = sin(B)/b = sin(C)/c
