Combining like terms is combining numbers with the same variables.
= -14 + 12 + 9z - 16z
= (-14 + 12) + (9z - 16z)
= -2 - 7z
~Put into standard form
-7z - 2
Best of Luck!
Answer:
-6/7
Step-by-step explanation:
-14+12+9z-16z=0
-6-7z=0
Add 7z to both sides
-6=7z
Divide both sides by 7
z=-6/7
Therefore the value for z is -6/7
.7 * 38.5 = original price
.7 * 38.5 = $26.95
your answer is 84,000
