A polynomial can have
constants
variables
exponents
that can be combined using addition, subtraction, multiplication and division ...
... except ...
... not division by a variable
2gallons/7people. This is the answer
Move 6x to the right side
2y = -6x - 14
Divide all numbers by 2 to isolate the variable
2y/2 = -6x/2 - 14/2
y = -3x - 7
4(2x-5)+15=11
8x-20+15=11
8x-5=11
8x=11+5
8x=16
x=16/8
x=2
