X^2-2=x
x^2-2+x=0
x^2+x-2=0
(x+2)(x-1)=0
Therefore, x+2=0 or x-1=0
Hence, x=-2 or x=1
Solutions= -2 or 1

Answer:
- The percentage of total votes received by Molly
- 58%
Step-by-step explanation:
a) We don't know what your menu choices are. The question is asking for the percentage of total votes received by Molly.
__
b) The total number of votes is 21 +29 = 50. Molly's fraction is 29/50. Expressed as a percentage, that is ...
29/50 × 100% = 58%
-7x - 2y = 19
4x + y = -12
Set y equal to each other (opposite signs are fine and you could also set x equal instead of y)
-7x - 2y = 19
8x + 2y = -76
Add equations together
x = -52
Plug x value into an equation
4(-52) + y = -12
Solve for y
-208 + y = -12
y = 196
Hope this helps! ;)
