Equation: x + 2 = 7/8x - 15
Solution: x = -136
<u>Explanation</u><u>:</u>
x + 2 = 7/8x - 15
2 + 15 = 7/8x - x
17 = 7/8x - 8/8x
17 = -1/8x
17 × -8 = x
-136 = x

Which means there's a 1/2 or 50% chance of it landing on one or the other

Step-by-step explanation:
Firstly, set the x value as 0:
-0 + 2y = 2
2y = 2
y = 1
So when x = 0, y = 1
Now set y to 0:
-x + 2(0) = 2
-x = 2
x = -2
So when y = 0, x = -2
Simply plot the two following points:
(0 , 1) and (-2 , 0)
And don't forget to join these two points up!

Answer: The number of yes votes = 1918.
Step-by-step explanation:
Given : The ratio of yes to no votes = 2:3
Then the ratio of yes to total votes =
Total votes = 4795
Number of yes votes = (ratio of yes to total votes) x (Total votes )
=
Hence, the number of yes votes = 1918.
