Solve for y
eliminate x
multiply firs tequation by -5 and 2nd by 3 and add them
-15x-30y=-15
<u>15x-3y=81 +</u>
0x-33y=66
-33y=66
divide both sides by -33
y=-2
the y coordinate is y=-2
X + 7/6 = 2x - 7/6
x + 7/6 (-7/6) = 2x - 7/6 - (7/6)
x = 2x - 14/6
x (-2x) = 2x (-2x) - 14/6
-x = -14/6
x = 14/6 or 2.33
x = 2.33
hope this helps
There would have to be a total of 32 contestants at the start of the show,
next round there were only 16
next 8
