Z - (-9) is the same as z + 9. Subtracting a negative is the same as adding.
Therefore
17 = z - (-9)
is the same as
17 = z + 9
To get 'z' all by itself, we need to subtract 9 from both sides. We subtract 9 from both sides to undo the "plus 9" occurring to the 'z' on the right side.
17 = z + 9
17-9 = z + 9=9 ... subtracting 9 from both sides
8 = z
z = 8
So the answer is z = 8
---------------------------
Check:
17 = z - (-9)
17 = 8 - (-9) ... replace z with 8
17 = 8 + 9
17 = 17
Answer checks out
Answer:
Step-by-step explanation:
Let the total amount of water the container can hold be . Currently, there are liters in the container. If Ito adds 10 liters of water, the container will be 60% full. We can express this statement in the following mathematical equation:
Next, we're given that if we add 6 more liters to this, the container will be 75% full.
Therefore, we have:
This is a system of equations:
Subtract both equations to conveniently get rid of :
Combine like terms:
Divide both sides by -0.15:
Now substitute into any equation (I'll choose the first):
Subtract 10 from both sides:
