Basically just add them all together like normal addition except there is a z attached to each number:
43z + 15z + 7z + 5z + 46z + 14z
58z+ 7z + 5z + 46z + 14z
65z + 5z + 46z + 14z
70z + 46z + 14z
116z + 14z
130z
Hope this helped!
Answer:
Explanation:
Since the all have z with a coefficient, they are all like terms
Factor out a z
(43 + 15 + 7 + 5 + 46 + 14 )z
Then add all the coefficients together
(130)z
The total is 130z
