Answer:
We put the value of the x in the formula

f(6)=

Step-by-step explanation:
Than solve equation.
There is no solution to this set that works for both equations. If you multiply the top equation by 2 and then add them together, the x and y numbers will cancel. This leaves you with 0 =1010, which is never true.
Answer:
-12u + 11z
Step-by-step explanation:
The above expression cannot be simplified, for:
1) There is no common variable (one being <em>u</em>, and the other being <em>z</em>).
2) There are no common factors in between 12 & 11)
- Factors of 12: 1, 2, 3, 4, 6, 12
- Factors of 11: 1, 11
