1. N + 2; n = 6: the answer is 8 because n=6 so we sub n with that... and we get 6+2 and that’s 8.
2.5f; where f=4: the answer is 20 because when a variable is directly next to a number it is multiplied by that number so we will replace f with 4 and our equation is now 5(4) or 5•4 and both are equivalent to 20.
3. 7b-2; where b=5: the answer is 33 because 7 multiplied by 5(b) minus 2= 7(5)-2 or 7•5-2= 33 because you will multiply 7 by 5 and get 33 then you will subtract by 2 and get 33.
Hope this helps!!!
Step-by-step explanation:
Now , divide both side by the same number...
Answer:
The last one 8
Step-by-step explanation:
X=-36
5/6x-1/2x=1/3x
1/3x-3=-9
1/3x=-12
x=-36
We have 
, to find inverse switch y and x then solve for y.
.
Hope this helps.
