Step-by-step explanation:
Answer:

Step-by-step explanation:
This is a subtraction between polynomials, since both functions are polynomials, hence, to solve the problem with need to perform the subtraction, by coefficients.

By performing the subtraction, we have:

Answer:
12x = 84
x = 7
Step-by-step explanation:
12x = 83 1/3 + 2/3
12x = 84
x = 84/12
x = 7
Hope that helps!
I think you guys are using a^2 + b^2 = c^2
the equation would be
x^2 + 2x^2 = 6^2
