Answer:
the first one im pretty sure
Step-by-step explanation:
Answer: the answer is -32
Step-by-step explanation: multiply -2 by itself 5 separate times.
The answer to the first one is:
x=-5/4y+-1/2. Why?
In the equation 8x+10y=-4, you subtract 10y form each side which leaves you with 8x=-10y-4. Right? Then you divide each side by 8 which gives you the answer
The answer to the second one is the same answer to the first problem. Why? Because you can already divide each side which gives you x=-5/4y+-1/2.
Hope this helps :^)
