Answer:
I think it is this because it seems as if It is 2 separate equations.
a.x=9-2y/3
b.x=3+y/3
Answer:
The concept or process is
.
Step-by-step explanation:
Consider the provided information.
The following property can be used to rewrite each radical as an exponent.
The numerator tells the power of the resulting rational exponent, and the denominator of the rational exponents tells the root of that number.
![x^{\frac{m}{n}}=(\sqrt[n]{x})^m](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D%3D%28%5Csqrt%5Bn%5D%7Bx%7D%29%5Em)
For example:
![(27)^{\frac{2}{3}}=(\sqrt[3]{27})^2](https://tex.z-dn.net/?f=%2827%29%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D%3D%28%5Csqrt%5B3%5D%7B27%7D%29%5E2)


Hence, the concept or process is
.
Step-by-step explanation:
to work out gradient
change in y ÷ change in x
first lines gradient
(7 - - 8) ÷ (7 - 7) = 0
second lines gradient
(7 - 7) ÷ (9 - - 6) = 0
Answer:y= 47/20
